Enterprise SAS drive for transactional workloads

The Dell 89D42 is a 1.2TB enterprise SAS hard drive built for 12Gb/s interfaces and 10.5K spindle speed. It fits 2.5-inch SFF bays in servers and storage arrays that demand consistent throughput for database and virtualization tasks. Installation should be performed by experienced technicians.

Sustained throughput at 10.5K spindle speed

The 10.5K rotation rate keeps sequential and random I/O steady during extended read and write sessions rather than peaking only in short bursts. The 12Gb/s SAS link moves data to the controller without the latency spikes seen on slower interfaces. This behaviour suits workloads that run continuously across multiple drives.

Thermal and acoustic profile in rack deployments

In normal rack operation the drive runs within enterprise temperature limits while drawing power typical for 10.5K 2.5-inch SAS units. Acoustic output stays at levels expected for high-speed spindle drives in dense chassis. No special cooling beyond standard server airflow is required.

商品問答

How much heat and noise does the 10.5K spindle generate during continuous operation?

The 10.5K rotational speed produces typical enterprise-level heat and audible seek noise; plan for active airflow in the drive bay.

What controller or backplane is required to run this 12Gbps SAS drive?

A SAS HBA, RAID card or server backplane that supports 12Gbps SAS signalling and the 2.5 SFF form factor is required.

Will the 1.2TB SAS drive work in an older 6Gbps SAS enclosure I already own?

Yes, the 12Gbps SAS interface negotiates down to 6Gbps, so the drive functions in a 6Gbps backplane at the lower speed.
