  • 15,000 RPM spindle speed for rapid data access

  • 3 Gb/s SAS interface connects to compatible controllers
  • Includes black series caddy for hot-swap installation

What this drive is

The Dell ST373355SS is a 73GB 3.5 inch SAS hard drive spinning at 15000RPM with a 16MB buffer. It includes a black hot-swap caddy for tool-less installation in compatible bays. The 3Gb/s interface suits enterprise servers and storage arrays that demand fast rotational speed.

Who it suits and who it does not

This drive fits servers and RAID enclosures that accept 3.5 inch SAS hot-swap trays and need high IOPS from a 15000RPM spindle. It is not for systems lacking a SAS backplane or controller, for builds requiring more than 73GB per spindle, or for situations where a 2.5 inch form factor is mandatory.

The deciding specification

The 3Gb/s SAS interface determines compatibility; the drive will only operate in a backplane or controller that supports this exact signalling rate and connector type. Verify the host platform provides native SAS 3Gb/s ports before purchase.
