The CRU® Rhino® Jr RJ24S enclosure is a sturdy four-bay removable drive enclosure that mounts in a standard 5.25-inch drive bay - like a CD ROM bay - and accepts four 2.5-inch hard disk drives or solid state drives. The drives used in a RJ24S enclosure operate independently which means each drive can be easily swapped out without affecting performance or functionality of the other drives. With keyed push button drive removal on the front of the unit, drive swapping is easy. With LED indicator lights for each bay and dual 35mm cooling fans, the RJ24S enclosure is a powerful addition for creating flexible storage in any system. Features Holds up to four 2.5-inch SAS or SATA drives (up to 15mm height) Uses scratchless connectors: each drive bay is rated for up to 50,000 insertion/removal cycles Each of the four drives has a dedicated power/drive activity LED and can be inserted or removed independently The RJ24S can be connected to JBOD or RAID controllers Compact storage enclosure that mounts inside any standard 5.25-inch drive bay
