New Thunderbolt 5 NVMe Storage Solution Revealed – The OWC 4M2 Ultra

OWC has introduced the Express 4M2 Ultra at NAB 2026 as a compact 4 bay NVMe enclosure built around Thunderbolt 5. It is designed as a DIY storage solution for users who want to install their own M.2 SSDs and configure the enclosure for different RAID modes, including RAID 0, 1, 4, 5, 10, and JBOD. OWC positions it as a high performance option for media production, post production, and other bandwidth intensive workloads that benefit from fast external solid state storage.

The enclosure supports up to 4 NVMe M.2 drives in 2280 or 2242 formats and is rated for up to 6622MB/s in RAID 0 when paired with PCIe 4.0 or newer SSDs on Thunderbolt 5 systems. It also retains backward compatibility with Thunderbolt 4, Thunderbolt 3 on Mac, and USB4 hosts, though throughput is lower on 40Gb/s connections. Capacity starts with whatever drives the user installs, with support for up to 32TB in a single unit based on current 8TB SSD support, while additional units can be daisy chained for larger storage pools.

OWC Express 4M2 Ultra – Design & Storage

The Express 4M2 Ultra uses a compact aluminum enclosure with a vertical desktop form factor intended to keep its footprint relatively small. OWC states that the chassis is built from aircraft grade aluminum, which serves both as the structural housing and as part of the thermal design. The unit measures 12.3 cm tall, 11.7 cm long, and 6.0 cm wide, with a listed weight of 900 g.

Internally, the enclosure provides 4 drive bays for NVMe M.2 SSDs and supports both 2280 and 2242 form factors. It accepts single sided and double sided drives, though SSDs with integrated heatsinks are not supported. OWC specifies support for PCIe Gen 3 and later SSDs, with Gen 4 and newer drives recommended for higher performance. Each bay operates at PCIe 4.0 x1, and single drive performance is rated at up to 1600MB/s.

From a storage flexibility standpoint, the enclosure is aimed at users who prefer to source and install their own drives rather than buy a preconfigured array. That allows the capacity and performance profile to vary depending on the SSDs installed. With current 8TB drives, the maximum listed capacity is 32TB in a single enclosure, while future higher capacity drives could increase that figure without requiring a new chassis.

RAID support is handled in software rather than through a dedicated hardware RAID controller. The Express 4M2 Ultra supports RAID 0, 1, 4, 5, 10, and JBOD, with OWC highlighting SoftRAID as its main management option. This gives users a wider range of configuration choices depending on whether they prioritize throughput, redundancy, usable capacity, or a balance between those factors.

Thermal management is handled by a 40mm cooling fan with multiple speed thresholds tied to internal temperature. According to OWC’s listed profile, the fan remains off below 35°C, then ramps progressively from 40% to 100% as temperatures rise from 35°C to 55°C and above. The stated approach is to reduce unnecessary noise under lighter workloads while maintaining SSD performance during sustained transfers.

OWC Express 4M2 Ultra – Ports and Connections

The Express 4M2 Ultra uses Thunderbolt 5 as its primary host interface, with 1 USB C host port rated for up to 80Gb/s. OWC also lists support for USB Attached SCSI Protocol, and the enclosure is designed to work across Thunderbolt 5, Thunderbolt 4, USB4, and Thunderbolt 3 on supported Mac systems. In practice, that gives it a broader compatibility range than a Thunderbolt 5 only accessory, though maximum throughput depends on the bandwidth available from the connected system.

A second Thunderbolt 5 port is included for downstream connectivity. OWC states that this allows users to daisy chain up to 5 additional Thunderbolt devices, along with 1 USB peripheral, from the same connection path. The same port can also be used to connect additional Express 4M2 Ultra units, with OWC positioning that as a way to build larger storage volumes without treating each enclosure as an entirely separate destination.

Compatibility varies by platform and interface generation. On newer Thunderbolt 5 Macs and PCs, OWC rates the enclosure at up to 6622MB/s, while Thunderbolt 4 and USB4 systems are listed at up to 3200MB/s. Intel Macs with Thunderbolt 3 are rated up to 2800MB/s, and OWC notes that Thunderbolt 3 support is Mac only. No driver is required, and the enclosure is listed as compatible with macOS 14.x Sonoma, macOS 15.x Sequoia, macOS 26.x Tahoe, Windows 11, and Linux, with some features depending on OS version and connection type.

OWC Express 4M2 Ultra – Price and Release date

OWC has set the starting price of the Express 4M2 Ultra at $399.99 for the standard non SoftRAID version. A version bundled with SoftRAID is priced at $549.99. As a result, the enclosure enters the market as a premium DIY storage option rather than a low cost external SSD enclosure, with the final overall build cost depending heavily on the NVMe drives a buyer installs.

The company says the Express 4M2 Ultra is available for pre order now following its reveal at NAB 2026 in Las Vegas. OWC lists shipping for Q3 2026, so early buyers will still be waiting several months for general availability. That places the launch window firmly in the second half of the year, even though orders have already opened.

New Cost-Effective USB4, M.2 and PCIe Adapters from IOCREST/Lekuo for 2026 Revealed

IOCREST, also marketed under the Lekuo name for consumer channels, is preparing a broader range of USB4, M.2, and PCIe expansion products aimed at users who need higher speed networking, storage expansion, or more flexible external PCIe connectivity. Based on the product information provided and the accompanying interview material, the current lineup combines shipping devices with several products still in development or not yet formally listed on the company’s official product pages, reflecting a portfolio that spans compact 10GbE adapters, SFP+ connectivity, multi-drive enclosures, and USB4 based PCIe breakout designs.

Lekuo USB4 to 10GbE Hub

Buy HERE on Amazon – Buy HERE on AliExpress

The Lekuo DTB3R61 is a compact USB4 hub that combines 10GbE networking with basic peripheral and removable media expansion in a single enclosure. It is built around a USB4 upstream connection and is intended for hosts that support USB4 or Thunderbolt 3/4/5, rather than older USB 3.x only systems. In practical terms, this positions it as a multi function dock for users who need wired 10GbE, a small number of USB ports, and SD or TF card access without moving to a larger desktop class dock.

The port layout is relatively simple, consisting of 1x 10GbE RJ45 port, 3x 5Gbps USB Type A ports, and a TF/SD 3.0 card reader. The supplied specifications list a 40Gbps host link, support for Windows, macOS, and Linux, and a compact metal chassis. Although your transcript refers to a fanless design, the specification sheet provided here states an aluminum alloy casing with fan assisted cooling, so that distinction should be treated carefully in the article unless you want to frame it as pre release versus final spec variation.

Lekuo USB4 to 2x25GbE Adapter

Buy HERE on Amazon – Buy HERE on AliExpress

This unreleased Lekuo adapter is one of the more bandwidth focused products discussed in the interview material, built around a USB4 host connection and 2x 25GbE network ports. Based on the information provided, the design uses an SFP based approach rather than RJ45, which is consistent with the higher thermal and signal demands of 25GbE. It is positioned as a compact external network adapter for systems that need significantly more throughput than 10GbE, while still relying on USB4 as the host side connection.

The transcript also indicates several design details that help distinguish this unit from more common USB or Thunderbolt network adapters. It is described as a silent design with no active fan, includes an external barrel power input, and features a physical power button on the enclosure. The company indicated that the product was expected around Q2 and priced below $200 at the time of filming, but as it is not yet listed on the official product page, those details should be treated as pre release guidance rather than final retail specification.

Lekuo DTB3F21 USB4 to 2x10GbE Adapter

Buy HERE on Amazon – Buy HERE on AliExpress

The Lekuo DTB3F21 is a dual port USB4 network adapter designed around 2x 10GbE SFP+ connections. Unlike simpler USB to Ethernet devices that target single port RJ45 connectivity, this model is positioned for users who need higher density fibre or DAC based networking from a single external enclosure. The supplied specifications identify the Intel 82599 controller, placing it closer to a traditional server class 10GbE design than a lower cost USB NIC.

From the product information and transcript, this adapter is part of Lekuo’s broader push into USB4 based external networking, especially for systems that lack internal expansion but still need multi port high speed network access. The enclosure is described as compact and externally connected over USB Type C, with support across Windows, Windows Server, Linux distributions, and several enterprise networking features such as VLAN support, jumbo frames, interrupt moderation, and virtual machine queue support. In the transcript, a dual 10GbE version is also discussed alongside the dual 25GbE model as part of the same general product family.

Lekuo M.2 to 10G SFP+ Adapter

Buy HERE on Amazon – Buy HERE on AliExpress

Lekuo is also developing an M.2 to 10G SFP+ adapter, extending the same general idea seen in its M.2 to 10GbE RJ45 products toward fibre based networking. In the transcript, this product is described as a refined version of an existing concept rather than a completely new direction, aimed at compact systems that only have an M.2 slot available for expansion. That makes it relevant for small servers, mini PCs, and embedded platforms where a full PCIe slot is not available but higher speed network connectivity is still required.

The main distinction here is the move from copper 10GbE to SFP+, which allows use of fibre modules or DAC cabling depending on deployment requirements. That gives the adapter a different role from the RJ45 version, particularly in longer distance links or environments already using SFP+ switching infrastructure. Based on your notes, this product is not yet available on the official product page, so the current information is limited to what was shown and discussed during the visit rather than a finalized retail specification sheet.

Lekuo USB4 to 2x PCIe Gen4 x1 Slots Box

Buy HERE on Amazon – Buy HERE on AliExpress

This unreleased Lekuo USB4 expansion box is designed to expose 2x PCIe slots from a single external USB4 connection, using the same basic enclosure approach shown on the company’s 8x 1GbE adapter. In the transcript, the unit is described as a small PCIe dock originally used internally for testing, with the USB4 connection bridging to 2 separate PCIe paths inside the enclosure. The concept is straightforward: rather than delivering fixed networking or storage, it provides a more flexible external PCIe breakout for users who want to install their own cards.

That flexibility is the main point of interest here. The transcript suggests use cases such as network cards, SATA cards, and other compact PCIe devices, with bus power available over USB4 and a barrel power input included for cards that need more power than the host connection can provide on its own. Since this product is not yet listed on the official product page, the available information is still limited and some details remain unconfirmed. The requested naming of this section as a PCIe Gen4 x1 slot box reflects the intended lane configuration you provided, but that specific wording was not fully documented in the supplied official specification text, so it should be treated as based on your product notes.

Lekuo USB4 to 4 HDD and 1x Gen4 M.2 Box

Buy HERE on Amazon – Buy HERE on AliExpress

Lekuo is also preparing a multi drive USB4 enclosure that combines 4 HDD bays with a single PCIe Gen4 M.2 NVMe slot in the same chassis. Based on the transcript, this is a DAS rather than a NAS, so it is intended to provide direct attached storage expansion over USB4 instead of functioning as a self contained network appliance. The inclusion of the M.2 slot adds a layer of flexibility beyond a standard 4 bay enclosure, allowing for SSD caching, a dedicated fast volume, or a separate high speed workspace alongside the hard drive array.

The product is described as relying on software RAID rather than including a hardware RAID controller, and the transcript also notes a dual port TB4 style design for daisy chaining. At the same time, the core concept is clear: this is an external storage enclosure aimed at users who want a mix of larger capacity HDD storage and faster NVMe storage within a single USB4 connected device. As with several of the other products shown during the visit, this unit does not yet appear on the official product page, so the available details should be treated as pre release rather than final retail specifications.

Lekuo USB Expansion PCIe Card

Buy HERE on Amazon – Buy HERE on AliExpress

Lekuo is also developing a PCIe expansion card that combines USB and storage connectivity on a single board, aimed at systems where slot space is limited and adding multiple separate controller cards is not practical. In the transcript, the card is shown with 2x USB Type C ports, 1x USB Type A port, 4x SATA ports, and an integrated 2.5GbE network connection. Rather than focusing on a single function, it is intended as a compact multi purpose expansion card for small form factor systems, embedded builds, or storage focused PCs that still need additional external connectivity.

The card is described as operating over a PCIe Gen4 x1 connection, giving it a total host side bandwidth of 20Gbps to allocate across its various controllers. That does not mean every port can run at maximum speed simultaneously, but it does make the board suitable for mixed duty use where SATA connectivity, modest USB expansion, and basic 2.5GbE networking need to be consolidated into one slot. Based on the material you provided, this product was shown during the visit rather than backed by a full standalone specification sheet, so some lower level details remain unspecified.

Lekuo USB4 to 10G SFP+ Adapter

Buy HERE on Amazon – Buy HERE on AliExpress

Lekuo is also expanding its external 10GbE range with a USB4 to 10G SFP+ adapter, offering an alternative to the more common RJ45 based 10GbE designs already associated with the brand. In the transcript, this model is presented as a silent SFP based version of the company’s existing copper 10GbE adapter, intended for users who want fibre or DAC connectivity instead of 10GBASE T. That makes it more relevant for rackmount environments, structured fibre deployments, and users already working with SFP+ switching infrastructure.

The product appears to share the same broader design language as the other newer USB4 network adapters shown during the visit, including a compact metal enclosure, ventilation at each end, and an external power option. The transcript also notes a physical power button on this family of devices, which is relatively uncommon on compact external network adapters. As this specific single port USB4 to 10G SFP+ model is not included in the supplied formal product specification sheets, the current information is based on what was shown and described in the video rather than a final retail listing.

Who Are IOCREST/Lekuo?

IOCREST and Lekuo are effectively 2 market facing identities used by the same company. Based on the interview material, the business was founded in 2000 and has operated for more than 20 years in adapter, connectivity, and expansion hardware design. IOCREST appears more closely associated with the company’s long standing OEM and B2B activity, while Lekuo is the branding now being pushed more directly toward end users and consumer retail channels.

A key point from the interview is that the company states that most of its products are designed in house, including the internal engineering and development work behind its USB, USB4, M.2, and PCIe based solutions. It also describes its product planning as being driven by practical gaps in the market, particularly in compact systems where users need to add networking, storage, or expansion features that are not available on the base hardware. That helps explain why many of its products focus on niche but increasingly relevant use cases such as M.2 to 10GbE, USB4 to multi port networking, and external PCIe breakout designs.

The other defining part of the company’s position is that much of its historical business has been behind the scenes. In the interview, Lekuo states that before its more recent consumer push, most of its sales were B2B, with products often sold through partners, distributors, or other companies without prominent IOCREST or Lekuo branding on the product listing itself. The current shift appears to be less about changing what it makes and more about putting its own name in front of products that were previously sold in a more anonymous OEM style model.

WE LOVE COFFEE

On connaissait Acemagic pour ses Mini PC accessibles… Le fabricant chinois confirme son ambition d’entrer sur le marché des NAS, à l’instar de Beelink. Pour cela, il lance un modèle hybride animé par un Ryzen Embedded R2544. Un choix qui peut surprendre sur le papier, mais qui s’avère finalement plutôt cohérent…

Acemagic N3A

Avec le N3A, Acemagic fait un pari simple : ne pas trancher entre mini PC et NAS. Le constructeur propose ici une solution tout-en-un capable de répondre à ces deux usages.

Il s’agit d’un boîtier intégrant 4 baies pour disques durs (ou SSD) ainsi que 2 emplacements M.2 NVMe en PCIe 3.0. Il est construit autour d’un processeur Quad Core AMD Ryzen Embedded R2544, avec iGPU intégré. Selon CPU Passmark, ce dernier obtiendrait 8 459 points.

Le produit est livré en version barebone, c’est à dire sans mémoire ni stockage. Il prend en charge jusqu’à 64 Go de DDR4, avec compatibilité ECC. C’est plutôt un avantage pour les usages orientés serveur et stockage.

Côté logiciel, il semble tourner sous la dernière version de Windows.

Un vrai hybride

Le N3A ne se limite pas à un simple rôle de NAS. Sa connectique complète lui permet aussi de fonctionner comme un mini PC classique.

On retrouve :

• 2 ports réseau : 2.5 GbE et 1 GbE
• 1 sortie HDMI 2.0
• 1 DisplayPort 1.4
• 1 port USB Type-C compatible vidéo
• 2 ports USB 2.0
• 2 ports USB 3.0 Type-A

Cette configuration permet de gérer plusieurs écrans ( y compris en 4K) et d’envisager des usages variés.

Prix et disponibilité

Le boîtier est d’ores et déjà disponible à la commande sur le site officiel pour 300€. À ce tarif, le N3A se positionne comme une alternative compétitive face aux NAS x86 traditionnels.

Sur le papier, le rapport capacité/prix est intéressant. Comme souvent avec ce type de produit, tout se jouera sur des éléments moins visibles : qualité du firmware, gestion thermique et niveau sonore.

La fiche technique semble solide et cohérente, mais c’est un produit qui devra faire ses preuves…

UniFi and the Airwire – Did Ubiquiti just SOLVE Everyone’s WiFi MLO Issue?

Ubiquiti has introduced the UniFi AirWire, a WiFi 7 client adapter designed to address one of the more limited areas of current WiFi 7 deployment: the client side. While WiFi 7 access points and routers have been marketed heavily around Multilink Operation, many currently available client devices still rely on single-radio implementations that switch between bands rather than maintaining simultaneous links. The AirWire is positioned as a dedicated external client that aims to deliver true STR MLO operation across 5 GHz and 6 GHz, with Ubiquiti claiming improved throughput, lower latency, and better resilience than conventional integrated client hardware.

At a hardware level, the AirWire is a USB-C connected WiFi 7 adapter with a 4-stream design, support for 5 GHz and 6 GHz 2 x 2 MU-MIMO operation, and a quoted uplink capability of up to 5.8 Gbps on 6 GHz and 4.3 Gbps on 5 GHz. It also adds a high-gain antenna design and a dedicated scanning radio for real-time spectrum analysis. At $199, this places it well above the cost of generic USB wireless adapters, but it is also targeting a more specific role: enabling multi-gigabit wireless client connectivity in environments that already have the access point infrastructure to support it.

You can buy the Airwire via the link below – doing so will result in a small commission coming to me and Eddie at NASCompares, and allows us to keep doing what we do! 

UniFi Airwire – Design

The UniFi AirWire has a noticeably different physical design to the compact USB WiFi adapters that are typically associated with desktop or laptop client upgrades. At 117 x 117 x 42.5 mm and 537 g, it is much closer in appearance to a standalone wireless bridge or directional client than a conventional dongle. That larger enclosure is directly tied to its intended function, as Ubiquiti is clearly building around higher power operation, larger antenna structures, and the thermal requirements that come with sustained WiFi 7 activity across multiple radios.

The housing is made of polycarbonate and includes a fold-out top section that appears to be part of the antenna assembly and directional positioning of the unit. This gives the AirWire a more deliberate deployment profile, where placement and orientation are likely to matter more than they would with an internal laptop radio or a low-profile USB adapter. On the front, there is also a 0.96-inch status display, which provides at-a-glance information during setup and operation without needing to rely entirely on software feedback from the host system.

From a practical standpoint, the design reflects that this is not intended to be an invisible add-on for casual wireless use. It is an external client device built to sit on a desk or near a workstation, with a form factor that prioritizes radio performance and signal handling over portability. That makes it less discreet than mainstream client adapters, but it also aligns with the product’s stated purpose as a high-performance WiFi 7 endpoint for users trying to push beyond the limitations of standard integrated wireless hardware.

UniFi Airwire – Internal Hardware

Internally, the UniFi AirWire is built around a dual-band WiFi 7 architecture that focuses entirely on 5 GHz and 6 GHz operation, without any 2.4 GHz support. Ubiquiti rates the device as a 4-stream client, split across 2 x 2 MU-MIMO on 5 GHz and 2 x 2 MU-MIMO on 6 GHz.

This layout is central to its stated role as an STR MLO client, allowing both bands to be active simultaneously rather than relying on the more common single-radio behaviour seen in many current WiFi 7 client devices.

Ubiquiti also specifies a high-gain antenna design, with 11 dBi quoted on both 5 GHz and 6 GHz, which is significantly more aggressive than the antenna arrangements found in most integrated laptop or mobile WiFi hardware. Alongside this, the AirWire includes a dedicated scanning radio for real-time spectral analysis. That separate scanning capability is notable because it suggests the unit is not just focused on link speed, but also on monitoring local RF conditions and interference in parallel with normal client operation.

The trade-off for that hardware approach is power and thermals. Ubiquiti lists maximum power consumption at 18 W, with USB PD 5/9/12V support and separate normal and performance power profiles. In practical terms, that places the AirWire closer to a compact external network appliance than a typical USB wireless adapter. It also helps explain the larger chassis, the need for external power flexibility, and the expectation that sustained performance operation will demand more cooling headroom than a smaller bus-powered client device could realistically provide.

UniFi Airwire – Connectivity

The UniFi AirWire connects to the host system over USB-C, but from a networking perspective it is presented as a 5 GbE interface over USB 3.2 Gen 2. That distinction matters, because although the wireless side of the device is rated far higher in combined theoretical bandwidth, the host connection places an upper practical ceiling on what can be delivered to the attached PC, laptop, or workstation. In effect, the AirWire is designed to behave more like an external multi-gig network adapter than a conventional USB WiFi dongle.

On the wireless side, the AirWire operates on 5 GHz and 6 GHz only, with support for WiFi 7, WiFi 6, WiFi 5, and 802.11n data rates across a wide range of channel widths. Ubiquiti lists support for EHT 20/40/80/160/240/320 MHz, alongside HE, VHT, and HT modes on earlier standards. The maximum quoted link rates are 5.8 Gbps on 6 GHz using 320 MHz bandwidth and 4.3 Gbps on 5 GHz using 240 MHz bandwidth, though actual results will depend heavily on access point capability, spectrum availability, regional channel restrictions, and signal conditions.

Power delivery is also part of the connection design. Ubiquiti specifies USB PD 5/9/12V support, with 15 W in normal mode and 20 W in performance mode, while maximum device power consumption is listed at 18 W. This means that, depending on how the host system is connected and powered, full performance operation may require more than a single low-power USB port can reliably provide. That makes cable quality, port specification, and available USB power budget more relevant here than they would be for standard client adapters.

The AirWire also includes support for wireless meshing and real-time spectral analysis, which extends its connection role beyond basic client access. In a UniFi environment, setup is intended to be handled through UniFi AutoLink for rapid onboarding, reducing the need for separate client-side software installation. Even so, the broader connection experience will still depend on the surrounding infrastructure, particularly whether the connected UniFi access point supports the required WiFi 7 and 6 GHz features needed for the AirWire to operate in the way it is being marketed.

UniFi Airwire – Verdict?

The UniFi AirWire is a more specialised product than its USB-C connection initially suggests. Rather than serving as a low-cost way to add basic WiFi 7 support to a system, it is designed to address a specific gap in the current client ecosystem: the lack of widely available true multi-radio MLO hardware on the device side. Its value therefore depends less on headline wireless specifications alone and more on whether the surrounding network environment is already capable of taking advantage of simultaneous 5 GHz and 6 GHz operation, wider channel support, and multi-gigabit client throughput.

On that basis, the AirWire appears to be an interesting but clearly targeted piece of hardware. The larger chassis, higher power requirements, directional design, and likely dependency on a strong WiFi 7 6 GHz deployment mean it is not a universal client upgrade for every user. However, for users already invested in UniFi WiFi 7 infrastructure and looking for a higher performance external client than the current mainstream market provides, it introduces a form factor and feature set that are still relatively uncommon. Whether that translates into a meaningful real-world advantage will depend on testing, particularly around sustained throughput, latency behaviour, thermal limits, and the practical impact of STR MLO outside of ideal conditions.

The GL.iNet Comet 5G is a remote KVM built to provide keyboard, video, and mouse control of a connected computer from power on through BIOS, rather than relying on a working operating system like traditional remote desktop tools. It accepts HDMI input from the host and offers HDMI passthrough so a local display can remain connected, with support up to 4K at 30 fps or 1080p at 60 fps, plus 2 way audio. Connectivity is where the Comet 5G differentiates itself most clearly in this product line: it can be managed over Gigabit Ethernet and Wi-Fi 6, but it also includes a nano SIM slot for 5G RedCap with 4G LTE fallback, intended for out of band access when the site network is down, segmented, or simply not trusted. It also supports a local AP mode that broadcasts its own wireless network for nearby management sessions without joining the surrounding LAN. In day to day use, the device is mainly aimed at remote maintenance tasks such as OS installs, recovery and imaging, BIOS changes, and support work on machines that lack built in management like iDRAC or iLO. Compared with the Comet Pro, it keeps the same general platform and interface approach, but adds the cellular path, the AP mode, a larger 3.69 in touchscreen, and 64 GB of eMMC storage for ISO and file staging. The key questions for a review are less about raw compute, since the core platform is similar to the Comet Pro, and more about whether the extra connectivity options, storage capacity, and on device usability justify its higher price for the way it will actually be deployed.

Gli.Net Comet 5G KVM Review – Quick Conclusion

The GL.iNet Comet 5G is essentially the Comet Pro style KVM experience with a stronger connectivity toolkit rather than a major jump in raw performance: you still get reliable BIOS level access, HDMI passthrough so a local screen can stay connected, and flexible access from a browser across different operating systems, but the main reason to choose it is the extra ways it can be reached when the local network is unavailable or not trusted. The nano SIM support (5G RedCap with 4G LTE fallback) gives an out of band route that can keep access available even when Ethernet or Wi-Fi are misconfigured, and the AP mode adds a direct nearby connection for quick point to point management without joining the site LAN, which can be genuinely useful in field work, segmented networks, or recovery situations. It also doubles the internal storage to 64 GB, which makes it easier to keep several ISO images and tools ready to mount remotely, and the larger 3.69 in touchscreen makes local setup and status checks less cramped. The trade offs are mostly about expectations: storage speeds remain modest, so uploading and copying large files is not fast; USB based storage expansion exists but is limited by USB 2.0, can require reboots, and drive compatibility is not always consistent; and while the device supports multiple paths and is marketed around failover, the current interface does not expose deep, router style controls for tuning how those paths behave. If you mostly run KVM over a stable wired or Wi-Fi network, the Comet Pro will usually cover the same core tasks for less money, but if you want a small KVM that gives you more options to regain access when networks are awkward or failing, the Comet 5G is the more complete tool as long as you accept the storage and configuration limitations.

Gli.Net Comet 5G KVM Review – Design & Storage

The Comet 5G follows the same general design language as the Comet Pro, but it is physically larger and more deployment focused. It measures 128 × 93 × 33 mm and weighs 285 g, which makes it more of a bag sized tool than something that disappears behind a monitor without planning. The casing relies on passive ventilation rather than active cooling, and in normal use it is intended to be left running continuously, provided it is powered independently rather than from the host machine.

A practical difference in the Comet 5G design is the addition of external antennas to support its wireless roles.

This includes cellular and Wi-Fi antennas, and the unit is clearly built around the expectation that it may be used away from a stable wired network, whether that is via the SIM slot or via a direct nearby wireless connection. In a fixed desk setup the antennas can feel like overkill, but for temporary installs and field support they suit the intended use case.

On the front, the Comet 5G uses a 3.69 in touchscreen, which is notably larger than the Comet Pro’s 2.22 in panel. In practice, that extra size does not materially change the experience of mirroring the host display on the device itself, since you remain limited by the source resolution and scaling.

Where it does help is in the local management interface, where menus and status screens have more room and are less cramped, particularly during setup or when checking network state and service toggles directly on the unit.

Storage is expanded to 64 GB eMMC, and the main advantage is capacity rather than speed. In use, the internal storage is primarily for keeping ISO images, recovery media, and utility files that can be mounted remotely as virtual media or exposed to the host as a remote drive.

File transfers to and from the internal storage typically sit in the same general performance range as the Comet Pro, which means it is functional for staging installers and smaller toolsets, but slow for moving large data sets.

A newer software feature available across the platform also allows external storage via a USB drive, but it comes with constraints that affect how usable it is in practice. Adding a drive can require a reboot, compatibility varies between drives, and the management interface tends to treat partitions individually rather than offering straightforward full disk handling.

Because the port involved is USB 2.0, external storage is more about adding space for additional ISOs than achieving a meaningful improvement in transfer speeds.

Gli.Net Comet 5G KVM Review – Connectivity

The Comet 5G keeps its I/O layout simple, with the core KVM connections built around full sized HDMI input and HDMI output for passthrough. This avoids adapter reliance and makes it easier to drop into existing setups where monitors and capture paths already use standard HDMI cabling. In a permanent install, passthrough is the more important part of that arrangement, since it allows a local user to keep working on the attached screen while remote access remains available in the background.

For host control, the unit presents USB based keyboard and mouse emulation over its USB-C connection, while power is also supplied via USB-C at 5V/3A with PD compatibility.

In practical terms, powering it from an independent adapter is the safer approach, because drawing power from the host machine can remove KVM access when the host is powered off, rebooting, or in a state where USB power is unstable.

Wired networking is provided by a 1 GbE RJ45 port, which is the most consistent option for image quality and responsiveness when the site network is stable. Alongside this, the Comet 5G supports Wi-Fi 6 on both 2.4 GHz and 5 GHz, and it also includes an AP mode that allows a direct nearby wireless connection without joining the surrounding LAN.

That AP mode is best understood as a local management path rather than a general purpose hotspot, and it is primarily useful when you want a quick point to point session for BIOS work or initial configuration.

The main connectivity addition over the Comet Pro is the nano SIM slot for cellular access, supporting 5G RedCap with 4G LTE fallback. This is positioned as an out of band route that can keep the management channel available when Ethernet and Wi-Fi are unavailable or misconfigured, and it also reduces dependence on VLAN routing rules and other site side constraints.

In the current software experience, the cellular side is exposed through its own configuration section, but it does not offer the same depth of policy and failover tuning found on GL.iNet’s router products.

Gli.Net Comet 5G KVM Review – Internal Hardware

Internally, the Comet 5G is built around a quad core ARM Cortex-A53 SoC paired with 1 GB of DDR3L memory, which is broadly the same class of platform used by the Comet Pro. In review terms, this means the Comet 5G is not trying to win on raw compute, but on connectivity and deployment options, because the core processing headroom is similar. The A53 class CPU is adequate for running the management services, handling multiple control sessions, and keeping the on device UI responsive, but it is not aimed at heavier workloads outside the core KVM functions. The OS is Linux 6.1, and the device behaves like a small embedded appliance rather than a general purpose system you would extend with additional packages and services.

The video path is designed around HDMI ingest and H.264 hardware encoding, with the remote stream adapting to available bandwidth and quality settings in the client interface. Support is listed up to 4K at 30 fps and 1080p at 60 fps, with HDMI passthrough keeping a local monitor active while the unit captures the same signal for remote viewing.

Audio is supported in 2 directions, but the device itself is not treated as a standalone audio endpoint, so the practical experience depends on how the host exposes audio over HDMI or USB and how the client session is configured. Input is handled via USB based HID emulation, which is why copy and paste and keystroke injection can sometimes behave differently between applications depending on how they interpret simulated typing versus clipboard shortcuts.

The storage subsystem uses 64 GB eMMC soldered to the board, and in practice it is tuned for predictable, mid range throughput rather than high performance. Real world transfer rates observed during ISO uploads and mounted storage tests typically sit around the mid 20s to mid 30s MB/s range, which aligns with the Comet Pro experience and reflects the limits of the flash and controller rather than a network bottleneck.

That makes it usable for staging installers, recovery media, and driver packs, but not ideal for repeated large image transfers or heavy file shuttling. Expansion is possible via a USB drive using the USB 2.0 Type-A port, but that is primarily a capacity extension, because USB 2.0 limits both bandwidth and available bus power, and drive compatibility can vary depending on the enclosure controller and power draw.

Gli.Net Comet 5G KVM Review – Software, Services & Performance

The Comet 5G uses the same GLKVM software family as the earlier Comet devices, with access provided through a browser interface, a desktop client, and a mobile app. In testing, the browser UI is the most straightforward for configuration and for working across different operating systems, and it also exposes most of the device settings without needing to install anything locally.

Firmware maturity differed slightly between units during side by side use, with the Comet Pro running a stable 1.8 release build while the Comet 5G was still presented as beta, though the overall layout and feature set were close enough that the differences felt tied to hardware options rather than a separate software branch.

#

Account and session security options are built into the platform, including 2 factor authentication and passkey support at the account level, plus the ability to apply an additional password gate per device before entering a remote session. Remote access can be handled locally over LAN, through GL.iNet’s relay service, or through peer to peer options. Tailscale support is part of the platform, and newer software revisions have also introduced ZeroTier support, which addresses earlier feedback around relying on a single remote access option.

For users who prefer not to use relay services, these VPN style paths can provide remote reachability without opening ports or depending on the vendor’s cloud beyond account management.

Where the Comet 5G differs in day to day software behavior is how cellular and nearby access are exposed. Cellular configuration appears as a dedicated section for SIM based connectivity, while the Wi-Fi settings include an AP mode that allows direct nearby connections without joining the site WLAN. In practice, these features improve the chances of reaching the device when the surrounding network is misconfigured or inaccessible, but the management interface does not currently provide the same depth of routing, policy control, or visible failover logic that GL.iNet includes in its router products. Multi path behavior is present at a feature level, but there is limited opportunity to tune it beyond selecting the available connection modes.

Performance during remote control sessions depends mainly on the network path and the host workload rather than differences between the Comet 5G and Comet Pro hardware. Video quality controls and stream settings allow the session to be made more stable on weaker links, and the general desktop experience remains usable for BIOS work, OS installs, and troubleshooting.

A copy and paste stress test with a large block of text showed both devices could transfer long input sequences, but the Comet 5G produced fewer odd spacing issues in the final pasted document during that run. On mobile, both devices provide touch mode and cursor mode plus access to a software keyboard, and external Bluetooth keyboards and mice can be used, but fluidity and compression artifacts were more noticeable when the phone was on cellular data compared with a local Wi-Fi or wired path.

Gli.Net Comet 5G KVM Review – Verdict & Conclusion

The Comet 5G works as a continuation of the Comet Pro platform rather than a clean break. The remote session experience, general interface layout, and core feature set remain familiar, because the underlying compute and encoding approach is broadly the same, and both devices are aimed at the same type of work: BIOS access, OS installs, recovery tasks, and remote troubleshooting where standard remote desktop tools are not enough. The areas that do change the day to day ownership experience are mostly around how you can reach the device when things go wrong. The SIM based 5G RedCap and 4G LTE fallback adds a separate management path, and the AP mode provides a direct nearby connection that avoids relying on the site LAN. The larger 3.69 in screen also makes the on device menus easier to use, even if it does not transform the usefulness of live video mirroring on the panel itself.

On the positive side, the Comet 5G is more adaptable in awkward environments, such as networks with strict VLAN boundaries, unreliable Wi-Fi, or unknown cabling, and it gives you more ways to regain access without a site visit. The 64 GB eMMC storage is also easier to live with if you keep multiple ISO images or toolkits available, although transfer speed remains limited and does not materially improve over the 32 GB model. On the less positive side, the cellular and multi path story is currently presented more as a capability than as a deeply configurable system, so users expecting router style failover policies and detailed controls may find the options relatively basic. The external storage expansion feature helps with capacity, but it is constrained by USB 2.0, requires reboots in some situations, and drive compatibility can be inconsistent, which limits how predictable it is as a long term workflow.

Overall, the Comet 5G is easier to justify when you expect to use the cellular connection or the nearby AP mode regularly, because those are the main reasons it exists and the main differences you will notice. If the device will live on a stable wired network most of the time and you only need a straightforward remote KVM for routine maintenance, the Comet Pro will usually cover the same core tasks for less money. If your priority is having multiple ways to reach the box when the local network is down or not trusted, the Comet 5G is the more complete tool, but its value depends on those deployment realities rather than any large jump in raw performance.
