Product Description

This BUSlink 2-Bay RAID SSD drive supports large capacity and USB 3.0/eSATA interface. It supports RAID 0 or RAID 1 depending on the model ordered. RAID 0 (striping) is faster and provides the full capacity (ie. 2TB x 2 = 4TB) but no backup. RAID 1 (mirroring) is slower and provides half the capacity (ie. 2TB x 2 = 2TB; 1 drive is used for backup). Removable HDD trays support hot-plug replacement of drives (only for RAID with redundancy mode). HDD intelligent sleep function is supported. Cooling fan maintain safe operating temperature. Skid proof and shockproof rubber feet mat ensure safe operation.
