RAIDDrive is designed to break the throughput bottleneck in the storage subsystem by removing the bandwidth limitation of the SATA bus. The PCIe x8 interface used by RAIDDrive SSDs supports 2GB/sec bandwidth, more than ten times that of the SATA-II 3Gbps bus, and five times greater than the not yet available SATA-III bus.

Using patent pending RAID architecture that is optimized for NAND flash memory, RAIDDrive is able to support burst read speeds of up to 1.4GB/sec. A turbocharged cache system with up to 1GB of DRAM cache enables burst write speeds as fast as 1.2GB/sec. RAIDDrive, which houses four discrete SATA SSDs, comes in a custom aluminum enclosure measuring 257 x 107 x 25.4 mm. Higher capacity RAIDDrive models use the RAIDDrive Expander - a separate PCIe card - to hold a total of eight SATA SSDs.
