Product overview
This is the Synology 3.84TB SATA SFF 2.5" Solid State Drive, order code SAT5221-3840G. Form factor and connector decide whether a drive physically lands in the bay; this is a SFF unit, and an adapter that fits mechanically can still cost you hot-swap. Give us the chassis and we will check the carrier as well as the drive.
Ask for the datasheet and firmware notes with the quote; we would rather you check our claim than take it.
