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.

Seagate Shows Off It’s 44TB Hard Drive at NAB 2026

At the 2026 NAB Show 2026, Seagate Technology formally introduced its latest generation of high-capacity enterprise hard drives built on the Mozaic 4+ platform. These drives, (model ID ST4400NM002M)  reaching up to 44TB, represent the current peak of commercially deployed hard disk capacity and are already being shipped to select hyperscale cloud providers. The announcement reflects ongoing demand for higher-density storage as data generation continues to accelerate, particularly in artificial intelligence and large-scale cloud environments.

Rather than targeting general consumers, these drives are designed specifically for hyperscale data centres where efficiency, density, and cost per terabyte are critical considerations. The Mozaic 4+ platform is also notable for its reliance on heat-assisted magnetic recording (HAMR), a technology that has moved from experimental development into production-scale deployment. With broader qualification underway, the 44TB model serves as both a milestone in current storage capabilities and a step toward projected capacities approaching 100TB in future generations.

Everything we know about the Seagate 44TB Hard Drives

The 44TB drives are built on Seagate’s Mozaic 4+ platform, which represents the company’s production-ready implementation of heat-assisted magnetic recording (HAMR). Unlike earlier perpendicular magnetic recording approaches, HAMR uses localized heating via a nanophotonic laser to temporarily reduce the coercivity of the disk surface, allowing data to be written at much higher densities. This enables significantly greater areal density without requiring a complete redesign of the underlying hard drive architecture, allowing Seagate to scale capacity incrementally across generations.

At a physical level, the drives use a multi-platter design, widely understood to consist of 10 platters, each delivering over 4TB of capacity. This results in the total 44TB figure within a standard 3.5-inch enterprise form factor. The spindle speed is expected to remain at 7200 RPM, consistent with other enterprise-capacity drives, balancing throughput, reliability, and power consumption. Early estimates suggest sustained transfer rates in the region of 300 MB/s, though final performance characteristics depend on deployment conditions and firmware tuning. I think we are likely much more liekly to hit 280MB/s or so, such as you find in the 30TBs.

A key aspect of the Mozaic 4+ design is its vertically integrated photonics system. Seagate has developed its own laser components in-house, embedding them directly into the recording head. This allows precise, nanosecond-scale heating during write operations, which is critical for maintaining data integrity at such high densities. Vertical integration also gives Seagate tighter control over manufacturing consistency, yield, and long-term reliability, all of which are essential when deploying drives at hyperscale volumes.

The recording stack itself incorporates several advanced components. These include a Gen 2 superlattice platinum-alloy media designed for improved magnetic stability, a Gen 2 plasmonic writer responsible for delivering the heat-assisted write process, and a Gen 8 spintronic reader that improves read accuracy from increasingly smaller data bits. Together, these components enable higher density while maintaining error rates and durability within enterprise requirements.

Supporting these physical advancements is a 7nm integrated controller, which manages drive operations with improved precision. This controller enhances servo control, allowing the read/write heads to maintain accurate positioning over narrower tracks. It also contributes to improved power efficiency, reducing watts per terabyte and helping data centres optimize energy usage at scale. These gains are particularly relevant in large deployments where power and cooling costs scale with capacity.

From a manufacturing perspective, the Mozaic platform is designed to scale without requiring disruptive architectural changes between generations. Each iteration builds on existing processes, allowing Seagate to increase per-platter capacity over time. The company has indicated a roadmap toward 10TB per platter, which would enable drives approaching 100TB within a similar physical footprint. This approach prioritizes continuity in deployment while steadily increasing storage density.

Seagate 44TB HDDs – SMR or CMR?

Despite the push toward higher capacities, the 44TB drives based on the Mozaic 4+ platform use conventional magnetic recording (CMR) rather than shingled magnetic recording (SMR). This distinction is relevant because SMR typically achieves higher capacities by overlapping data tracks, which can negatively impact rewrite performance and latency in certain workloads. By retaining CMR, Seagate is prioritising predictable performance characteristics, particularly for enterprise environments where consistent throughput and low latency are required.

This approach also differentiates Seagate’s offering from competing high-capacity drives, such as those being developed by Western Digital, which have explored SMR and related technologies like UltraSMR to reach similar capacity points. While SMR can be effective for archival or sequential workloads, CMR remains better suited to mixed or write-intensive applications commonly found in hyperscale deployments. In this context, the use of HAMR allows Seagate to increase density without relying on SMR trade-offs, maintaining compatibility with existing data centre workloads and software stacks.

The introduction of 44TB hard drives based on the Mozaic 4+ platform reflects a continued focus on increasing storage density within the constraints of existing data centre infrastructure. By combining HAMR with incremental architectural improvements, Seagate Technology has demonstrated that higher capacities can be achieved without fundamental changes to form factor or deployment models. The emphasis remains on scaling capacity per rack and per watt, which aligns with the operational priorities of hyperscale environments.

At the same time, these drives remain firmly positioned within enterprise and cloud use cases, with limited relevance to consumer or small-scale storage in the near term. Factors such as cost, workload requirements, and integration complexity restrict their adoption outside large data centres. However, as with previous generations, advancements at this level are likely to influence broader storage markets over time, particularly as manufacturing scales and newer technologies mature.

New UniFi UDM Beast, Enterprise FG Core, Enterprise 100G and Enterprise S Revealed

At NAB 2026 in Las Vegas, Ubiquiti Inc. showcased a number of rackmount UniFi devices that have not yet been formally announced or released. These systems were presented alongside existing products, making it necessary to distinguish between current hardware and what appears to be forthcoming or experimental equipment. The devices observed represent a noticeable increase in port density, throughput capability, and overall positioning compared to the current UniFi lineup.

Four specific devices stand out from this showcase: the UniFi Dream Machine Beast, the Enterprise Fortress Gateway Core, the Enterprise 100G switch, and the Enterprise S PoE switch. Based on available observations and supporting information, these products appear to form a cohesive expansion of the UniFi ecosystem into higher-performance enterprise and datacenter environments. However, specifications remain unconfirmed and should be considered provisional until officially published.

UniFi Dream Machine BEAST – A 25GbE UDM!

The UniFi Dream Machine BEAST appears to be a significant evolution of the existing Dream Machine platform, extending beyond the capabilities of current models such as the UniFi Dream Machine Pro Max. Based on observed hardware, this device integrates substantially higher port density, particularly in 10G and 25G connectivity, while also introducing onboard storage via dual SATA bays. This suggests a continued emphasis on combining routing, switching, and application hosting within a single appliance, including UniFi OS services such as Protect and other controller-based functions.

Compared to previous Dream Machine models, the BEAST shifts closer toward an enterprise-focused deployment, particularly in environments requiring direct multi-gigabit connectivity without reliance on additional aggregation switches. However, key system details such as CPU architecture, memory capacity, and throughput performance remain unconfirmed. The absence of official documentation indicates that this device is still in a pre-release or prototype stage, and its final positioning within the UniFi portfolio is not yet defined.

UniFi Enterprise Fortress Gateway Core – Truly Enterprise

The UniFi Enterprise Fortress Gateway Core appears to extend the capabilities of the existing UniFi Enterprise Fortress Gateway into a significantly higher performance tier. While the current Enterprise Fortress Gateway is already positioned as a high-end UniFi routing platform, the Core variant introduces substantially greater port density and bandwidth, including support for 100G connectivity. This suggests a shift from traditional edge gateway roles toward deployment in core or aggregation layers within larger enterprise or datacenter environments.

The observed hardware indicates a design focused on high-throughput routing and multi-layer network integration, with a combination of 10G copper, 25G SFP28, and 100G QSFP28 interfaces. This represents a notable departure from existing UniFi gateway designs, which typically rely on lower port counts and external switching for aggregation. As with the Dream Machine BEAST, critical specifications such as processing architecture, memory configuration, and pricing remain undisclosed, reinforcing the likelihood that this device is still in a pre-release stage.

UniFi Enterprise 100G – Next-Level Connections

The UniFi Enterprise 100G appears to be a high-density aggregation or spine switch designed for environments requiring large-scale bandwidth distribution. Its configuration, centered around 25G access ports and 100G uplinks, aligns with common leaf-spine architectures used in enterprise and datacenter networks. Within the current UniFi portfolio, the closest comparison would be aggregation-focused switches such as the UniFi Switch Enterprise Aggregation, although the observed specifications of this device significantly exceed existing models in both port count and total throughput capacity.

This device is likely intended for deployment deeper within network infrastructure rather than at the edge, acting as a central switching layer connecting multiple high-speed access or distribution switches. The combination of 48 × 25G and 6 × 100G ports suggests a focus on scalability and backbone connectivity rather than end-device access. As with the other devices observed, no official documentation, pricing, or detailed hardware specifications have been released, and its final role within the UniFi ecosystem remains unconfirmed.

UniFi Enterprise S – PoE Powerhouse

The UniFi Enterprise S appears to be a high-density access switch focused on multi-gigabit connectivity and high-power PoE delivery. Its configuration combines a large number of 2.5G and 10G copper ports, all supporting PoE+++, alongside 25G uplinks for upstream connectivity. Within the current UniFi lineup, there is no direct equivalent, although products such as the UniFi Switch Pro XG 48 PoE operate in a similar space with lower overall port density and more limited PoE capability. The Enterprise S extends this concept by standardising high-power PoE across all access ports.

This design suggests deployment in environments with dense endpoint requirements, including wireless access points, cameras, and AV equipment, where both bandwidth and power delivery are critical. The combination of 2.5G and 10G ports allows for flexibility across different device classes, while the inclusion of 25G uplinks supports integration into higher-speed aggregation layers. As with the other devices observed, there is no confirmed information regarding total power budget, internal hardware, or release timeline, and the device should be considered pre-release.

---

The four devices observed at NAB 2026 indicate a broader shift in the UniFi portfolio toward higher-performance networking tiers. Collectively, they introduce increased port density, support for 25G and 100G connectivity, and in some cases, significantly expanded power delivery capabilities. Compared to currently available products such as the UniFi Enterprise Fortress Gateway and UniFi Dream Machine Pro Max, these systems represent a move beyond traditional edge and SMB-focused deployments into roles typically associated with enterprise core, aggregation, and high-density access layers.

However, all four devices remain unannounced and lack confirmed specifications, pricing, and release timelines. As a result, their final positioning and availability cannot be determined with certainty. While the observed hardware suggests a structured expansion into a more complete end-to-end networking stack, any conclusions remain provisional until formal details are released by Ubiquiti Inc..
