4 TB 7.2K SAS 6 Gb/s LFF drive
This 3.5 inch internal hard drive delivers 4 TB of storage on a SAS 6 Gb/s interface spinning at 7 200 RPM with a 128 MB buffer. It ships new in an original Dell caddy and carries the Dell part number 9ZM270-150 alongside the manufacturer model ST4000NM0023.
Suits Dell PowerEdge servers listed.
The drive is validated for PowerEdge R310, R320, R410, R415, R420, R510, R515, R520, R710, R720, R720xd, T310, T320, T410, T420, T610, T620 and T710 systems. Builders whose chassis or controller accept only a different interface or a smaller form factor must select another part.
SAS 6 Gb/s interface decides fit
The single specification that determines compatibility is the 3.5 inch SAS 6 Gb/s connection; verify that your server backplane and RAID controller support this exact interface before purchase.

Questions about this item
What SAS controller or backplane must my system provide for the 3.5" SAS 6Gb/s interface?
The drive needs a SAS 6Gb/s backplane or HBA with a 3.5-inch drive bay; Dell PowerEdge R310, R410, R510, R710, T310, T410, T610 and T710 models include the required backplane.
Will the 7200RPM spindle speed and 128MB cache work with older 3Gb/s SAS backplanes in legacy PowerEdge servers?
The 7.2K RPM drive negotiates down to 3Gb/s on older backplanes, so it spins up in R310, R410, R510, R710, T310, T410, T610 and T710 systems, though sustained throughput stays at the lower link rate.
How can I confirm the ST4000NM0023 mechanism is recognised and healthy after installing it with the supplied R-series caddy?
In the PERC or HBA BIOS the drive should appear as a 4TB SAS device at 6Gb/s (or 3Gb/s on older controllers); run a SMART short self-test and verify zero reallocated sectors to confirm health.
