We heard you loud and clear (pun intended) when you said you loved everything about the Express 4M2 but wanted it quieter. After adding smart adaptive fans that only turn on when needed for near silent operation, we decided to give it USB4 connectivity for the optimum blend of compatibility, performance, and affordability. Now you can build a desktop/shuttle high-performance RAID with your choice of NVMe M. 2 SSDs and get up to 3200MB/s performance with USB4, Thunderbolt, and USB-C Macs and PCs.

The OWC Express 4M2 is a four-bay USB4 (40Gb/s) enclosure for user-installed NVMe M.2 SSDs, designed for creative professionals who need fast external storage or a DIY RAID setup; it supports 2230, 2242, and 2280 drives and offers up to 3200MB/s real-world performance. SSDs are sold separately.
Recommended For
- Video editors and post-production teams who keep active 4K/6K projects, large media libraries, or scratch files on a desktop NVMe RAID and want high-throughput storage they can configure with their own SSDs.
- DITs and filmmakers who need to offload media from multiple camera cards on set to a high-capacity desktop or shuttle RAID, and can work with a powered enclosure rather than a pocket-sized drive.
- Photographers and creative professionals who routinely move or edit large RAW photo catalogs and want to build storage capacity from separately purchased M.2 NVMe SSDs.
- Mac and PC users building a shared high-speed storage workflow who have a compatible USB4 or Thunderbolt 4/5 connection and are comfortable setting up a software RAID.
Real-World Use Scenarios
- A video editor sets up multiple NVMe drives as a RAID work volume to edit high-bitrate or multi-stream 4K/6K footage from an external drive; on a USB4 or Thunderbolt 4/5 host, the array can keep storage from becoming a bottleneck in demanding timelines.
- A digital imaging technician or camera crew offloads footage from several cards between takes; a configured NVMe array provides a fast external destination for consolidating media before post-production.
- A photographer keeps a large Lightroom catalog or active image projects on external storage; the enclosure’s multiple SSD slots let them build a high-capacity work volume, while fast access can make browsing and transferring large photo sets more responsive.
- A creator uses external storage for editing caches, scratch files, or frequently accessed project assets; multiple NVMe drives in a RAID configuration can provide a faster workspace than a single-drive setup, subject to the host connection and RAID configuration.
- A user with spare compatible M.2 NVMe SSDs builds a desktop storage array instead of buying a preconfigured external drive; they choose the drives and RAID setup to suit their capacity or performance needs, then connect the enclosure to a compatible Mac or PC.
