Description
Seagate Barracuda 7200.8 250GB 7.2K SATA Hard Drive ST3250823AS - Factory Recertified
These drives provide the following key features:
•7,200 RPM spindle speed.
•8 Mbyte buffer
•High instantaneous (burst) data-transfer rates (up to 150 Mbytes per second).
•Tunneling Giant Magnetoresistive (TGMR) recording heads and EPRML technology, provide the drives with increased areal density.
•State-of-the-art cache and on-the-fly error-correction algorithms.
•Native Command Queueing with command ordering to increase performance in demanding applications.
•Full-track multiple-sector transfer capability without local processor intervention.
•Quiet operation.
•300 Gs nonoperating shock.
•SeaTools diagnostic software performs a drive self-test that eliminates unnecessary drive returns.
•Support for S.M.A.R.T. drive monitoring and reporting.
•Supports latching SATA cables and connectors.
