The 8TB G-SPEED eS PRO External Hard Drive Array from G-Technology is an external hard drive array, designed for use in mission-critical applications. As configured, the array offers an impressive 8TB of storage spread across 4 physical drives. The array features no internal hardware RAID controller, and as such requires a dedicated mini-SAS RAID controller to function. G-Technology's included PCI Express x8 controller card can host 2 G-SPEED eS PRO units. It is capable of RAID 0, 1, 3, 5, and 6 configurations.
