  • SAS 12 Gb/s interface enables fast host transfers
  • 128 MB cache buffers burst workloads
  • GEN14 caddy fits listed PowerEdge servers

4TB 7200RPM SAS drive with GEN14 caddy

This Dell enterprise hard drive provides 4000GB of storage in a 3.5 inch form factor. It spins at 7200RPM and connects via a 12Gbps SAS interface with 128MB of cache. The included GEN14 caddy allows direct installation into compatible server bays.

Suited for PowerEdge GEN14 servers.

The drive is validated for PowerEdge models including R240, R340, R440, R540, R640, R740, R940, R740XD, R730xd2, R6415, R7415, R7425 and C6420. It requires a SAS-capable backplane and controller; systems without SAS support cannot use this drive.

12Gbps SAS interface determines fit

The drive operates on a 12Gbps SAS connection, so the host controller and backplane must support this signalling rate. Buyers should verify their server's drive bay and controller specification before purchase.

Questions about this item

Will the SAS interface or the 128MB cache need servicing during the drive's life?

The SAS 12Gbps interface and 128MB cache are sealed inside the drive; neither requires user maintenance or scheduled replacement.

Which limit appears first when the ST4000NM0295 runs sustained write workloads?

The 7200RPM mechanical speed governs sustained throughput, so the platter rotation rate becomes the bottleneck before the 12Gbps SAS link saturates.

How much heat and noise does the 4TB 7200RPM SAS drive produce in a GEN14 caddy during all-day operation?

The 3.5-inch 7200RPM mechanism generates typical enterprise-level heat and acoustic output; the included GEN14 caddy ensures proper airflow in supported PowerEdge bays.
