Dell W328K 146GB 15K SAS drive

The Dell W328K is a 146 GB 2.5-inch internal hard drive spinning at 15000 RPM with a 16 MB buffer. It uses a 6Gb/s SAS interface and is supplied as a bare drive in new condition. This unit targets server and workstation environments that demand high spindle speed in a small form factor.

Integration into Dell PowerEdge

The drive fits 2.5-inch hot-swap bays in listed PowerEdge models such as the R610, R710, R720, R810, R910 and T610 as well as Precision R5500 workstations. It also slots into PowerVault MD1120 and MD3200 direct-attached enclosures. A SAS backplane or RAID controller with 6Gb/s support is required; the drive frees a 3.5-inch bay for other uses.

Sustained workload behaviour

At 15000 RPM the platters maintain consistent rotational velocity under continuous read-write streams typical of database and virtualisation loads. The 16 MB cache absorbs burst I/O while the SAS protocol handles command queuing for multiple concurrent requests. Mechanical latency stays predictable during extended duty cycles unlike variable-speed alternatives.

Questions about this item

What is the spindle speed limit that defines sustained performance for the W328K?

The drive spins at 15000 RPM, which is the mechanical ceiling for its sustained data rate.

How much heat and noise does the 15000 RPM SAS drive produce during all-day operation?

A 15000 RPM SAS drive runs hotter and louder than slower drives; the server chassis must provide sufficient airflow.

Which Dell servers and workstations are confirmed compatible with the W328K part number?

Supported systems include Precision R5500 and PowerEdge models such as M610, M620, R610, R620, R710, R720, R810, T610, T710 plus MD1120 and MD3200 storage arrays.
