2.5" HDD/SSD Disk Array 4 (model: AE4RT25S)

~ Install as many as four 2.5" SATA/SAS hard drives or SSDs into a standard 5 1/4" drive bay
~ Support SATA I / II / III or SSD with drive height up to 15 mm
~ Light weight brushed aluminum construction



The new Addonics 2.5" Disk Array is a high density removable hard drive system that supports installing up to four 2.5" SATA/SAS hard drives upto 15 mm height or 2.5" SSDs into one standard 5.25" drive bay. This compact form factor makes this Disk Array an ideal solution for increasing hard drive storage in small computers, mini ATX systems or for applications that require large number of drives. Once the drive is mounted onto the removable drive tray, the drive can then be easily slided into or removed from the Disk Array unit, similar to using a VHS cassette. Eeach drive slot is equipped with its own power and drive access LEDs as well as a lock on the drive tray to secure each hard drive in the Disk Array unit.
