The UltraDrive GX extreme performance SATA-II SSD uses an advanced new controller and 64MB DRAM cache to deliver exceptionally fast sequential read and write speeds. With no moving parts, the GX is lightweight, uses far less power and is much more resistant to shock and vibration than a hard disk drive. The UltraDrive GX is also packed with all the latest performance and reliability features. ECC, wear leveling and bad bit management algorithms improve reliability and extend the life of the drive. The GX is available in capacities up to 256 GB with.
