Questions about this item

Does my server or workstation need a 3.5" SAS 6Gb/s backplane or HBA to use the ST1000NM0023?

Yes, the drive connects through a 3.5" SAS 6Gb/s interface and requires a compatible SAS controller or backplane with a free SAS port and power connector.

Can the 1TB 7200RPM SAS drive share a SAS controller with older 3Gb/s SAS drives?

The ST1000NM0023 supports 6Gb/s SAS and will negotiate down to 3Gb/s on the same controller, so it can operate alongside older SAS drives on a shared HBA.

After installation, how can I verify the drive runs at 7200RPM with the 128MB cache active?

Check the drive’s reported rotational speed and cache size in your RAID controller BIOS, operating-system disk utility, or SMART data; both should show 7200RPM and 128MB.
