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.
