• ST3400832NS

• ST3400632NS

• ST3250823NS

• ST3250623NS

These drives provide the following key features:

• 7,200 RPM spindle speed.

• 8 Mbyte buffer on ST3400832NS and ST3250823NS models;

 

16 Mbyte buffer on ST3400632NS and ST3250623NS models.

• High instantaneous (burst) data-transfer rates (up to 150 Mbytes per second).

• Tunneling Magnetoresistive (TMR) recording heads.

• 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. See Section 4.3.3.1 for additional information about SCT.

• 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.
