Sapphire Dual Drive Enclosure

The Sapphire Dual Drive enclosure is a compact size, light weight, low power and high performance external storage device. Up to two 2.5" hard drives or SSD can be added into this enclosure just like using a tape cassette, no special tool or tray required.  Come with built-in 6G 2-port Hardware Port Multiplier, the two drives can be configured to form a RAID 1, RAID 0, a large drive or as two individual drives. The enclosure can be attached to any system via eSATA port or the ubiquitous USB 3.0/2.0 port. It is ideal for adding a simple RAID storage or for expanding the storage capacity of a system or computing equipment. 

Constructed in a light weight sturdy aluminum housing with an integrated cooling fan for efficient heat dissipation, the Sapphire Disk Array is a great portable storage solution for a wide range of applications that demand high performance and reliable storage out in the field. Using the optional Addonics NAS 4.0 adapter, the two drives can be instantly turned into a Network Attached Storage equipment for sharing over the network.
