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

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.

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.
