OWC Express 4M2 USB4 (40Gb/s) Four-Slot NVMe M.2 Enclosure

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.

Maximum Speed from Your Machine

The Express 4M2 is the fastest multiple NVMe SSD enclosure we offer and was purposefully built so you can utilize the maximum performance capability of your Mac or PC with full compatibility:
