Enterprise drive identity

This is a Seagate Constellation ES.2 bare drive with 2TB capacity, 7200 RPM spindle speed and 64MB cache. It uses a SAS 6Gb/s interface in a 3.5 inch form factor and is built for 24×7 operation in server environments.

Suitability profile

The drive suits administrators who need a high-reliability SAS disk for continuous workloads in storage arrays or servers. Buyers who require a different interface or a larger capacity should consider other options.

Deciding specification

The SAS 6Gb/s interface is the single factor that determines compatibility; the drive will only function with a SAS host bus adapter or a controller that explicitly supports SAS signalling.

Questions sur cet article

What real-world throughput does the SAS 6Gb/s interface on the ST32000645SS deliver?

The SAS 6Gb/s interface caps at 6Gb/s transfer rate; actual sustained throughput depends on the 7200 RPM platters and 64MB cache, and will be lower than the interface maximum.

What physical space and mounting does the 3.5" ST32000645SS require?

The drive uses a standard 3.5" form factor and fits any 3.5" drive bay with SAS backplane or cable connectors; no tray is included with this bare drive.

How is the ST32000645SS installed in a server, and what step is often missed?

Mount the bare drive in a 3.5" bay, attach SAS data and power cables, then configure the drive in the RAID or HBA BIOS so the OS can see the 2TB volume.
