For users with specific high-performance storage requirements or if you simply have deep pockets, a PCIe SSD is the way to go. The bandwidth provided by the PCIe interface far exceeds that of SATA and thus provides greater storage performance.
Super Talent has just announced its next-generation PCIe SSD, the RAIDDrive II Plus. This PCIe SSD houses up to eight discrete SSDs and features 1GB of onboard DDR2 cache. It can also be configured to work in a variety of RAID configurations for performance and redundancy, allowing users to achieve in excess of 28000 MB/s of throughput.
The RAIDDrive II Plus will be available in 480GB, 1TB and 2TB capacities.
