OWC Express 4M2 Ultra: Redefining High-Speed Creative Workflows

WOODSTOCK, IL – July 23, 2026 – Other World Computing (OWC) has launched the OWC Express 4M2 Ultra, a compact, four-bay NVMe RAID solution built on the next-generation Thunderbolt 5 standard. The device promises to eliminate data bottlenecks for creative professionals, offering sustained speeds up to 6622MB/s and capacities reaching 32TB in a single unit. This release positions OWC at the forefront of a new wave of high-performance peripherals designed to handle the immense data demands of 8K and 12K video production, complex visual effects, and high-resolution photography.

Announced as the fastest compact ready-to-run Thunderbolt 5 NVMe RAID solution, the Express 4M2 Ultra is aimed squarely at production houses, post-production studios, and independent creators who can no longer afford to have their workflows constrained by storage speed. The move signifies a critical upgrade from previous Thunderbolt 4 and USB4 technologies, effectively doubling the available bandwidth and unlocking the true potential of multi-drive NVMe arrays.

The New Benchmark for Performance

The headline figure for the Express 4M2 Ultra is its staggering 6622MB/s performance claim. This speed is achieved by harnessing the 80Gbps bidirectional bandwidth of Thunderbolt 5, combined with four NVMe M.2 SSDs running in a RAID 0 configuration. For professionals, this translates into a tangible reduction in project turnaround times. The ability to smoothly scrub through multiple streams of 8K video or render complex 12K RAW files without dropping frames is a game-changer. On set, a Digital Imaging Technician (DIT) could offload a full day's worth of footage from multiple cameras in a fraction of the time required by older solutions.

Contextualizing this speed is crucial. While Thunderbolt 4 was limited to 32Gbps of PCIe throughput, Thunderbolt 5 doubles this to 64Gbps, allowing devices like the 4M2 Ultra to finally overcome the bandwidth ceiling that previously throttled multi-drive NVMe performance. The result is a desktop RAID solution that rivals the speeds of internal PCIe-based storage. OWC's choice to offer pre-configured, ready-to-run systems using its own Aura Ultra SSDs is a strategic move to guarantee this performance out of the box, a key differentiator for studios that prioritize reliability and immediate deployment over custom builds.

However, the market for extreme speed is not without its contenders. DIY-focused enclosures from brands like Acasis have demonstrated that with the right combination of PCIe Gen 5 NVMe drives, speeds can even exceed 19,000MB/s. Yet, such setups require significant technical expertise and sourcing of individual high-cost components. OWC's value proposition lies in delivering a certified, turnkey system that provides immense speed without the complexities of a custom build.

Future-Proofing with the Thunderbolt 5 Ecosystem

The launch of the Express 4M2 Ultra is timed to coincide with the growing adoption of Thunderbolt 5 in host devices. With the standard now appearing in Apple's latest M-series MacBook Pros and high-end Windows laptops, a robust ecosystem of compatible peripherals is essential. By investing in a Thunderbolt 5 device today, studios are not just buying a product for current needs but are future-proofing their infrastructure for the next generation of cameras and media formats.

Thunderbolt 5's “Bandwidth Boost” feature, which can dynamically allocate up to 120Gbps for display-heavy workflows, further enhances its appeal for video editors and VFX artists who often work with multiple high-resolution monitors. The Express 4M2 Ultra leverages this ecosystem by including a second Thunderbolt 5 port, enabling users to daisy-chain up to five additional Thunderbolt devices. This allows for massive storage expansion—up to 128TB by linking four 32TB units—or connecting high-resolution displays and other peripherals through a single port on the host computer.

"We have always believed that technology should adapt to the way people work… not the other way around," said Larry O'Connor, Founder and CEO of OWC, in the official announcement. This philosophy is evident in the product's design, which offers both a simplified, ready-to-run experience and the flexibility for power users to build their own solution with a bare enclosure option. This dual approach acknowledges the diverse needs of the professional market, from large studios requiring standardized, warrantied hardware to independent creators who prefer to fine-tune their own rigs.

Strategic Positioning and Value Proposition

With pricing that ranges from $2,399.99 for a 4TB model to a formidable $10,299.99 for the 32TB flagship, the Express 4M2 Ultra is a significant investment. Its value proposition must be weighed against its direct competitors and the cost of a comparable DIY build. Promise Technology, another veteran in the professional storage space, has entered the market with its Pegasus5 series, offering similar speeds in an eight-bay configuration. OWC competes by emphasizing its compact four-bay form factor and its proprietary SoftRAID engine, which provides robust RAID management capabilities (RAID 0, 1, 4, 5, 10, and JBOD).

The option to purchase a bare enclosure for under $600 (with SoftRAID) presents a compelling alternative for those with the technical know-how to source their own drives. However, the pre-configured models offer the assurance of a system where all components are tested and certified to work together seamlessly, backed by OWC's warranty and support—a critical factor for mission-critical professional workflows where downtime equals lost revenue.

Ultimately, the OWC Express 4M2 Ultra is more than just an external drive; it's a strategic business asset. Its aircraft-grade aluminum chassis provides both durability and passive cooling, supplemented by a smart fan for sustained heavy loads, ensuring performance remains consistent during marathon rendering or backup sessions. As project files continue to swell in size and complexity, integrated, high-bandwidth solutions like the Express 4M2 Ultra are transitioning from a competitive advantage to an operational necessity for studios aiming to stay at the forefront of media production.
