The CRU DataPort® DP41 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. The drives used in a DP41 enclosure operate independently which means each drive can be easily swapped out without affecting performance or functionality of the other drives. With easy push button drive removal on the front of the unit, it makes drive swapping easy. With 10 LED indicator lights and dual 4cm quiet magnetic levitation fans, the DP41 enclosure is a powerful addition for creating flexible storage in any system.
