Server-grade SAS drive

The Dell HT953 is a 300GB 3.5" internal hard drive spinning at 15000 RPM with a 16MB cache. It uses a SAS 3Gb/s interface and delivers a 4.5ms average seek time. Designed for server environments, the drive ships with a tray and packing may vary. Condition is refurbished.

Thermals and power

Enterprise 15000 RPM SAS drives generate more heat and noise than typical desktop drives and draw higher power under load. Plan for active airflow in the drive bay and ensure the chassis cooling can handle sustained operation. A SAS-compatible backplane or controller is required for connection.

Capacity constraint

The 300GB capacity limits this drive to operating-system, application or high-speed scratch volumes rather than bulk storage. Buyers who need more storage per bay should consider larger-capacity SAS models. The SAS 3Gb/s interface also restricts use to controllers and backplanes that support that signalling rate.

Questions about this item

How do I install the Dell HT953 3.5" SAS drive in a server tray and what step is often missed?

Mount the drive in the supplied tray, connect the SAS 3Gb/s data and power cables, then ensure the backplane or controller detects the 300GB 15000 RPM unit before initializing the array; the step often missed is confirming the SAS link speed in the controller BIOS.

What maintenance or replacement will the Dell HT953 300GB 15000 RPM drive need over time?

As a refurbished 15000 RPM mechanical drive with 16MB cache, plan for eventual bearing or motor wear; monitor SMART reallocated-sector counts and replace the unit once error rates rise or the 4.5ms seek time degrades.

Which limit appears first on the Dell HT953 300GB SAS drive during sustained write workloads?

The 3Gb/s SAS interface caps sustained throughput well below the 15000 RPM media speed, so the interface bottleneck shows up before the 16MB cache or 4.5ms seek time can be saturated.
