3.5in SAS 6Gb/s 3TB enterprise drive

This 3.5-inch internal hard drive delivers 3000GB of storage with a 7200RPM spindle and a 128MB cache. It connects through a SAS 6Gb/s interface and is supplied as a new, original Dell part numbered 9ZM278-150. The drive is built for integration into compatible PowerEdge servers.

Suited for PowerEdge servers listed

The drive fits the R310, R320, R410, R415, R420, R510, R515, R520, R610, R620, R710, R720, R720xd, T310, T320, T410, T420, T610, T620 and T710 models. It is not for systems that require a different physical interface or a form factor other than 3.5-inch LFF. Buyers needing a smaller drive or a different protocol should look elsewhere.

SAS 6Gb/s interface determines compatibility

The single specification that decides fit is the SAS 6Gb/s interface on a 3.5-inch LFF tray. Only controllers and backplanes that support this exact interface and form factor can use the drive. Verify the server or enclosure accepts SAS 6Gb/s LFF drives before ordering.

Questions about this item

Does the 9ZM278-150 ship with mounting brackets or cables, or must they be ordered separately?

The drive is supplied as a bare 3.5in unit; mounting brackets and SAS data or power cables are not included and must be sourced separately.

How do I choose between the 3TB capacity and other available sizes for a PowerEdge R720?

The 3TB model provides 3000GB at 7200RPM with a 128MB buffer; select a larger capacity only if you need more raw space for the same spindle speed and interface.

What does the 7200RPM spindle speed mean for daily use in a PowerEdge T620?

The 7200RPM rotation gives faster random access than slower near-line drives, making the 3TB SAS unit well suited for mixed read and write workloads in a T620.
