IcyDock MB994SP-4S Four-bay 2.5-inch SATA/SAS Hard Drive Rack Review
 

Unless you have a swanky PC case, it's usually not very easy to install a couple 2.5" notebook-sized hard drives into a desktop computer system.... until now. Instead of slap-hazzard approaches and cheap brackets, consider a hard drive rack that squeezes several small 2.5" drives into one single 5.25" bay slot. The IcyDock MB994SP-4S is just such a unit - it packs four 2.5" HDD/SSD drives into the space of a single 5.25" DVD drive and provides unified power and supported SATA hook ups at the rear.
