The Best DIY RAID You Wanted
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 Power of Choice is Yours
Engineered to support any NVMe M.2 2230, 2242, or 2280 SSD, this compact powerhouse gives you the ultimate flexibility to choose the drive you want today — including OWC Aura SSDs with up to a massive 8TB capacity each. When tomorrow’s 16TB and larger drives hit the scene, you can easily boost your Express 4M2’s capacity.

One Cool RAID for Diverse Workflows
High speed backups, multiple media card offloads, and intense RAW photo and 8K video editing sessions mean one thing… Heat. You can put aside any thermal throttling and noise concerns because the Express 4M2 utilizes a heat dissipating solid aluminum body along with smart, adaptive fans that activate only when needed or under heavy load. Diversity of use also means being able to easily work cross-platform with Macs and PCs. We help you keep your cool in mixed environments with our MacDrive software (avaialble separately).

Your Data’s Reliability is Our #1 Priority
Anyone can put a bunch of components in a housing and call it an enclosure or a drive. OWC is not just anyone. We’re a group of filmmakers, musicians, designers, content creators, and parents just like you wanting to capture and preserve that irreplaceable moment. Our data storage products go through countless hours of ongoing development testing and certification processes. We then subject them to extreme real-world abuses. The priority for some storage devices is to be a mass-produced, lowest price commodity. We do it differently because the reliability of your data and the longevity of an OWC product is priority #1.
