SiForce Big Drive IIA eSATA is a selectable hardware RAID enclosure for two 3.5" SATA HDD. A true hardware solution, SiForce Big Drive IIA requires no software to be installed on your machine.

It provides multiple hardware RAID mode:

• RAID 1 (Mirroring): for two disks with same capacity.
• RAID 0 (Striping): for two disks with same capacity.
• Spanning: for two disks with different capacity.
