ADATA Technology today announced the launch of the XPG SX300 and Premier Pro SP300 mSATA solid state drives. The XPG SX300 (SandForce SF-2281) has a SATA 6Gbit/sec interface, and is targeted towards power users. Read and write speeds are specified at 550 and 505 MB/sec respectively, with maximum 4K random write of 85,000 IOPs. The drive is available in the capacities of 64, 128, and 256GB.
The Premier Pro SP300 (LSI SandForce SF-2141) has a SATA 3Gbit/sec interface, and is an economical upgrade option. Read and write speeds are specified at 280 and 260 MB/sec respectively, with maximum 4K random write of 46,000 IOPs. Capacities of 24, 32, and 64GB allow for use in conjunction with a larger but slower mechanical drive.
The implementation of optimized firmware in the SX300 and the SP300 results in full utilization of the NAND Flash components, which translates to maximized storage capacity: a 7% increase over other solid state drives that use a SandForce controller. This zero percent over-provisioning is implemented with no loss to performance or supported features, and can be realized only by 100% screening and sorting of the NAND Flash. Both the SX300 and the SP300 are applicable to Intel Smart Response Technology, and comply with ATA/ATAP1-7 standard.
Supported features include S.M.A.R.T and NCQ command sets, and TRIM command. The drives are covered by a 3-year warranty and a MTBF (mean time between failures) of 1,200,000 hours. No pricing information has been released yet.
