ts USP is the SandForce SF-1200 SSD controller. With its MLC NAND chips, the controller can churn out transfer speeds of 200 MB/s read, and 141 MB/s write. When used with Windows 7 operating system, the SSDs offer TRIM support, a feature which uses idle time to erase deleted data which could otherwise consume many write cycles, also working towards reducing data fragmentation.
