Seagate ST3250823NS 250GB 3.5in 3Gbps 7.2K RPM HS NL NL35 Series SATA HDD – Refurbuished

Seagate ST3250823NS 250GB 3.5″ 3Gbps 7.2K RPM HS NL NL35 Series SATA HDD – Refurbuished

This drive provides 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 Magneto resistive (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.
  • Supports S.M.A.R.T. Command Transport (SCT) to provide enterprise-like features in an industry-accepted transport mechanism.
  • Supports the Write Same command to allow large writes without host interface overhead.
  • Supports Error Recovery Control to allow the host to put a soft time limit on read and write commands.
  • One-Step Microcode Download which allows enterprise clients to download new drive code with a single download command using the host download utility.
  • Workload management features to manage drive temperature and activity. This optimizes drive reliability in nearline environments with no user intervention required.
