Dell 10 TB SAS drive for server storage

This Dell ST10000NM0256 provides 10 TB of storage on a 3.5 inch form factor with a SAS interface. It spins at 7200 RPM and uses 512e sector formatting for broad compatibility. The drive is designed for nearline workloads in enterprise arrays and storage servers. It ships new in retail or OEM packaging depending on supply.

Sustained throughput on 12 Gb/s SAS link

The 12 Gb/s SAS connection supports consistent data rates during long sequential reads and writes typical of backup, archiving and surveillance recording. At 7200 RPM the mechanical latency remains stable across extended duty cycles. Nearline firmware optimises write caching for steady streaming rather than bursty random I/O. Thermal output stays predictable in multi-drive enclosures.

Verify SAS controller and bay clearance

Confirm your host bus adapter or RAID controller exposes a 12 Gb/s SAS port and that the backplane or cabling matches the 3.5 inch drive carrier. The 512e logical sector size requires an operating system and controller firmware that present 512 byte sectors to applications. This drive is not suited for desktop PCs lacking SAS infrastructure or for laptops needing 2.5 inch form factors.

Questions about this item

How much power does the 7200 RPM SAS drive draw during all-day operation?

The 10 TB SAS drive spins at 7200 RPM with a 12 Gb/s interface; typical idle power is around 7.2 W and active power under sustained load reaches roughly 10 W.

What host controller and cabling are required to run this 12 Gb/s SAS drive?

You need a SAS HBA or RAID card that supports 12 Gb/s speeds and a compatible SAS data cable; the drive uses a standard 3.5 in SAS connector and 512e sector format.

Will the 10 TB 512e SAS drive work in an older server that only has 6 Gb/s SAS backplanes?

Yes, the 12 Gb/s SAS interface negotiates down to 6 Gb/s on legacy backplanes, so the drive will operate at the slower link speed while retaining its 10 TB capacity.
