Icy Dock MB971SP-B " Duo Swap" 2.5"/3.5" SATA Hot Swap Drive Caddy External docking stations are popular because of its flexibility & compatibility. However, because it is for external use, the interface limits the transfer speed of your hard drive while only allowing one to be use at a time. In a standard computer case, there are several 5.25 bays usually reserved for your DVD ROM drive, however, will not naturally fit with your 2.5 or 3.5 hard drives without some assistance. We also want to create a much faster & smoother transition from external to internal setups.

The Duo Swap changes all of this as it is a 5.25 hot swappable drive caddy for 2.5 & 3.5 SATA hard drive or SSD. The MB971SP-B has the most flexibility within a single 5.25 device bay allowing different hard drive combinations, featuring the ability to fit a single 2.5, 3.5 or even both hard drives at the same time to produce the maximum storage capability. Inserting two drives into the Duo Swap gives you many benefits. With two drives inserted you can easily make backups of your 2.5 to your 3.5 drive or cloning your 3.5 to your 2.5 drive via SATA speed.
