  • 16 MB cache buffers burst I/O workloads
  • Includes black-series caddy for tool-less 3.5" bay installation

73 GB 15000 RPM SAS enterprise drive

This 73 GB SAS hard drive spins at 15000 RPM with a 16 MB buffer. It fits a standard 3.5 inch bay and uses the SAS 3Gb/s interface. The unit is new and built for enterprise workloads that demand consistent throughput.

Included black-series caddy

The supplied black-series caddy lets the drive slide directly into compatible Dell drive bays without extra brackets. No additional mounting hardware or software is bundled with the drive. Installation is a simple mechanical fit.

Verify SAS controller and bay spacing

Confirm that your server or workstation has a SAS backplane or controller that supports 3Gb/s operation. Check that the 3.5 inch bay accepts the Dell caddy form factor. Ensure the system can supply adequate cooling for a 15000 RPM enterprise drive.

Questions about this item

Will the SAS 3Gb/s interface or the 15000RPM spindle need service or replacement down the line?

The mechanical spindle and bearings are the wear items; the SAS 3Gb/s interface itself is solid-state and does not degrade, so only the drive mechanism may eventually require replacement.

Which limit appears first during sustained use — the 3Gb/s SAS bus or the 16MB cache?

The 3Gb/s SAS bus caps sustained throughput at roughly 300MB/s, while the 16MB cache fills in milliseconds, so the interface bandwidth is the first bottleneck under continuous load.

How much heat and noise does the 15000RPM 3.5" mechanism produce when running all day?

A 15000RPM 3.5" enterprise drive generates noticeable whine and measurable heat; it requires forced airflow in the chassis to stay within safe operating temperatures.
