Designed to fit 4 x Orico M2PV-C3 (M.2 NVME SSD).
It should also take the Orico M2PF-C3 & M2PVM-C3 cases.

I have fitted 4 of the M.2 cases into this caddy so that I can utilise them as a travel archive for photography. (See https://github.com/outdoorbits/little-backup-box - README.md) using the Little Backup Box as the basis for the Photo backup archive.

These simply slide into the caddy, it's a snug fit so they should not slide out in travel. Each bay is numbered so you know which one you have backed up to. Large open port for cooling using the finned enclosure case.

It's just designed to keep them all together and make the whole process easy to manage.
