Enterprise Performance 10K v7 Specifications




The Seagate Enterprise Performance 10K v7 comes in a standard 2.5" form factor with a 15mm z-height. The 10K v7 is available in only one capacity, 1.2TB, with the 10K v6 series offering smaller capacity 10K HDD options. The 10K v7 features four glass substrate platters with eight heads and an areal density of 538bit/sq.


The 10K v7 delivers sustained speeds of 204 MB/s, an average latency of 2.9ms, and 64MB of programmable multi-segmented cache. Logical block sizes are user-configurable at 512, 520, 524, or 528 bytes per logical block.


The RAID Rebuild feature enables faster recovery from a failed drive in a RAID configuration. RAID Rebuild improves performance by extracting easily readable data from a failing drive by identifying blocks that would take longer to recover from the failed drive than to rebuild from parity data in the RAID array. This minimizes the likelihood of a second drive failure in the array during rebuild and allows host control of error recovery.


Seagate's Instant Secure Erase reduces the time required to overwrite the drive from hours to less than a minute, speeding the process of repurposing or retirement of the drive. Protection Information (PI) technology provides an end-to-end data protection scheme that prevents data corruption from the application level down to the drive.


T10-compliant Seagate PowerChoice technology enables users to tailor systems for optimal performance and power usage. The average operating power for the 1.2TB model we are testing today weighs in at 4.65W. The v7 sports an AFR (Annualized Failure Rate) of 0.44%, an MTBF of 2.0 million hours, and a five year warranty.
