Hot-Swap Hard Drive Bay for 2.5" SATA SSD / HDD
- USB 3.1 (10Gbps) Enclosure
Product ID: S251BU31REM
This hot-swap hard drive bay turns your 2.5" SATA hard drive or solid-state drive into a removable drive
that you can use as a regular external USB 3.1 enclosure.
Hot swap your SATA storage
Mount the removable SATA drive bay into any 3.5" or 5.25" front bay, to provide a hot-swappable mobile
rack. This makes it easy to install and remove the drive from the computer system without having to open
the case every time, and provides a more convenient way to create backups that you can remove for data
recovery and archiving.
Make your data portable
If you need access to your data outside of the office, you can use the enclosure portion as a standard USB
3.1 (10Gbps) enclosure -- a powerful external storage solution when you need access to your files while
you’re on the road.

Simply eject the enclosure from the bay for portable data storage. Its lightweight, compact design makes
it easy to tuck into a laptop bag or carrying case. The enclosure includes a Micro-USB to USB-A and a
Micro-USB to USB-C cable, so you can plug the enclosure into your laptop and access your data anywhere
you go.
Add scalability to your storage
For even more versatility, StarTech.com offers the S251BU31REMD, an extra 2.5" SATA Drive Enclosure
for the S251BU31REM, providing multiple enclosures that can be swapped in and out of the main
computer.
The S251BU31REM backed by a StarTech.com 2-year warranty and free lifetime technical support.
