Solid State Drives use flash memory & as such offer high data transfer rates (read/write speeds) when installed in a notebook or desktop PC. There are no moving parts in an SSD which means they require less power to operate. Lower power consumption gives longer notebook usage time & because there are no moving parts the drive operates silently. Offering even higher performance on SATA-III based systems, Verbatim SATA-III SSDs take full advantage of the SATA-III bandwidth & are capable of achieving Read & Write speeds of over 500MB/second*. Verbatim SATA-III SSDs feature the widely acclaimed Sand Force 2281 controller; which incorporates advanced wear leveling, sophisticated EDC/ECC, & garbage collection algorithms to maintain stable & reliable performance. The SATA-III SSD is shock & vibration resistant making it more durable in harsher environments, & offers faster system performance than a standard hard drive. Verbatim SATA-III SSD feature SMART (Self Monitoring & Reporting Technology) command support, Trim command support (Windows 7), & Native Command Queuing (NCQ) support.
