Plextor PX-256M3S 256 GB M3S SATA 6GB/s Solid State Drive True Speed - an exclusive technology providing consistent high performance in real-life computing environments for the lifetime of the product. Unlike the competition, Plextor SSDs sustain read/write speeds for the life of the drive. Server-grade Marvell 88SS9174 controller chip for read/write speeds of up to 510MB/s and 360MB/s in sequential mode, and 70,000 and 65,000 IOPS for random read/write operations at 4K file size The M3S fully supports SATA 6Gb/s and is backward compatible with SATA 3Gb/s and SATA 1.5Gb/s The DDR3 DRAM cache transfers data faster and helps extend lifetime of the product The latest synchronous MLC NAND flash modules from Toshiba further enhance product reliability Smart firmware combines three advanced technologies to sustain performance: Bad Block Management, Global Wear Leveling, and Instant Restore. Bad Block Management and Global Wear Leveling optimize the way data is written on the drive and Instant Restore is a technique that overcomes the problem of declining speed after prolonged usage The M3S supports advanced functions such as S.M.A.R.T. failure prediction, the TRIM command, NCQ optimization, and superior Garbage Collection to further increase performance and reliability Five-year ironclad warranty provides reassurance of Plextor quality standards
