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 8.0TB capacity each. When tomorrow’s 16TB and larger drives hit the scene, you can easily boost your Express 4M2’s capacity.

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(sold separately).

Express 4M2 is ideal for:

DITs and Filmmakers wanting to build an affordable yet high-performance NVMe SSD RAID with up to 32TB of capacity, RAID 5 capabilities, and the ability to deliver maximum offload speeds and thermal stability when backing up media cards from multiple cameras on set.

Anyone looking for a lower cost RAID option to the award-winning four NVMe M.2 based OWC ThunderBlade and are willing to accept the Express 4M2’s larger form factor, fan cooling, no additional connectivity ports, and no ballistic shipping case for shuttle use.
