OWC Express 1M2 USB4 / Thunderbolt 4 NVMe M.2 SSD Enclosure – 40Gb/s

The Fastest Portable Storage You Can Hold in Your Hand

Plug in your NVMe M.2 SSD and experience what 40Gb/s actually feels like. The OWC Express 1M2 is built for professionals, creators, and power users who can't afford to wait — whether you're offloading 4K RAW footage on set, moving massive project files between machines, or running a bootable OS from an external drive.

The all-aluminium ribbed enclosure isn't just striking to look at — those fins are a fully functional passive heatsink, drawing heat away from your drive silently and continuously, so your SSD stays cool and performs at its peak even during sustained transfers.
