BitMICRO, which has transitioned their emphasis from the much smaller military SSD market, is focusing on high capacity drives as one of their key differentiators, and the new Z-Series SSDs go up to 8.8 TB.
The enterprise SSD space is a very congested one, but BiTMICRO believes that it can differentiate itself from this crowded field because while they focus on IOPS, BiTMICRO focuses on capacity.
