4TB SAS drive for Dell PowerEdge

This 3.5 inch internal hard drive delivers 4000GB of storage on a 6Gb/s SAS interface. It spins at 7200RPM with a 128MB buffer and ships new with a Dell PowerEdge caddy included. The drive fits directly into supported server bays without an extra tray.

Capacity and sustained throughput

Four terabytes provide room for operating systems, databases and bulk archives on a single spindle. The 7200RPM speed and 128MB cache keep sequential reads steady for backup targets and near-line workloads. Random I/O will saturate before the interface does, so heavy transactional loads need more spindles or flash.

SAS 6Gb/s interface limits

The 6Gb/s SAS link caps maximum burst transfer at the bus level, not the media. Real-world sustained rates sit well below that ceiling because the platters cannot feed data fast enough. The drive works in the listed PowerEdge models from the R310 through T710 families, but it will not negotiate 12Gb/s speeds on newer backplanes.

Questions about this item

Will the ST4000NM0023 4TB SAS drive work in my older PowerEdge R310 or T410 server?

Yes, the drive is listed as compatible with PowerEdge R310, R320, R410, R415, R420, R510, R515, R520, R710, R720, R720xd, T310, T320, T410, T420, T610, T620 and T710 servers.

How can I verify the ST4000NM0023 is running at 7200RPM and detected on the 6Gb/s SAS link after installation?

Check the server BIOS or RAID controller interface during POST; it should report the model ST4000NM0023, 4000GB capacity, 7200RPM speed and a negotiated 6Gb/s SAS link rate.

Does the ST4000NM0023 come with the Dell PowerEdge caddy, or do I need to buy a 3.5" tray separately?

The drive includes the Dell PowerEdge caddy/tray, so no separate 3.5" tray purchase is required for supported servers.
