Enterprise 3 TB SAS drive

This Seagate Constellation ES.2 model delivers 3 TB of storage on a 3.5 inch form factor with a SAS 6Gb/s interface. It spins at 7200 RPM and carries a 64 MB cache for sustained throughput in multi-drive arrays. The unit is supplied new and built for continuous 24×7 operation in server environments.

Suited for RAID arrays and bulk storage

Buyers deploying SAS-based servers or external JBOD enclosures will match the drive’s native interface and firmware tuning. Systems that lack a SAS backplane or hardware RAID controller cannot use this drive, so desktop builders without that infrastructure should look elsewhere.

SAS 6Gb/s interface decides fit

The single specification that determines compatibility is the SAS 6Gb/s connection; the host must present a matching SAS port or expander. Average seek time is 8.5 ms, average write time is 9.5 ms and average latency is 4.16 ms, figures that confirm enterprise-class responsiveness.
