FAQs
What distinguishes ST32000645SS from ST32000444SS?
Both are 2TB 7.2K SAS 6Gb/s LFF drives; the 645SS variant may include T10 PI, larger cache, or newer Constellation ES.3 firmware.
Does T10 PI add overhead to drive performance?
T10 PI adds minimal overhead since it is handled by drive firmware; the performance impact is negligible in most workloads.
What is the maximum sustained transfer rate?
The ST32000645SS achieves up to 185 MB/s sustained sequential reads, one of the highest rates for enterprise SAS HDDs.
Can this drive be used in EMC VNX storage arrays?
Yes, Seagate Constellation ES.3 drives are qualified for EMC VNX, Isilon, and other enterprise storage platforms.
Is dual-port SAS required for RAID configurations?
Dual-port SAS is not required for RAID, but enables multipath I/O for higher availability in SAN-attached environments.
