IcyDock 4-Hard Drive 2.5inch to 5.25inch Removable Kit

This bay from Icy Dock allows easy access to multiple 2.5" drives, via a tray system with hot-swap capabilities. The enclosure is built to fit up to four 2.5" SATA drives - either traditional hard drives or solid-state drives - and the whole array fits into a single 5.25 inch bay. Installed drives are cooled by a pair of small fans, but those can be turned off if using solid state drives (SSDs) that don't put off much heat.
