4 TB SAS Nearline Drive

This 4 TB SAS hard drive is built for nearline workloads where consistent capacity and 12 Gb/s interface bandwidth matter more than peak throughput. It suits storage arrays, backup targets and secondary data volumes that must stay online without the cost of all-flash media.

Sustained 7200 RPM Operation

The spindle runs at 7200 RPM continuously, so sequential transfers hold steady across long write or rebuild sessions instead of throttling after a short burst. SLC flash assists metadata handling, keeping latency predictable when the drive is hammered for hours at a time.

Thermal and Power Profile

In normal operation the drive draws only the power required for the 3.5" mechanism at 7200 RPM, with no extra controllers or accelerators adding heat. Acoustics stay at typical nearline levels, letting the unit sit in standard server chassis without demanding special cooling.

Questions about this item

How much heat and noise does the 7200 RPM SAS drive generate during continuous operation?

The 7200 RPM spindle speed produces typical nearline drive acoustics and warmth; ensure your chassis has adequate airflow for 3.5" bays.

What controller or backplane is required to run this 12Gb/s SAS drive?

You need a SAS HBA, RAID card or server backplane that supports 12Gb/s SAS links and 3.5" drive bays.

Will this 12Gb/s SAS drive work in an older 6Gb/s SAS enclosure?

Yes, the drive negotiates down to 6Gb/s on legacy SAS backplanes while retaining full 4TB capacity.
