Dell EqualLogic 900GB 10K SAS Drive

This Dell EqualLogic ST900MM0168 is a 900GB 2.5in internal hard drive spinning at 10000RPM with a 12Gbps SAS interface and 128MB cache. It is sold as a lot of 10 new drives for enterprise storage arrays or servers needing high-throughput block storage.

Suited for multi-drive array builds.

The lot-of-10 packaging suits administrators populating or expanding EqualLogic arrays and similar SAS backplanes. Buyers needing only a single spindle or a different capacity point should look elsewhere, as the product is supplied in this fixed quantity.

12Gbps SAS interface determines controller

The drive connects via a 12Gbps SAS link, so the host controller or backplane must support that signalling rate. Verify the system accepts 2.5in SAS drives before purchase, as the interface is the deciding factor for fit.

  • 900 GB capacity stores large datasets
  • 10 000 RPM spindle speeds up data access
  • 12 Gbps SAS interface moves data quickly

Questions about this item

What controller or backplane do I need to run the 12 Gb/s SAS interface on this 2.5 in drive?

A SAS controller or backplane that supports 12 Gb/s signalling is required; the drive uses a standard 2.5 in SAS connector.

Will this 10 000 RPM SAS drive work in an enclosure that only negotiates 6 Gb/s?

Yes, the SAS interface auto-negotiates down to 6 Gb/s, so the drive will operate at the slower link speed.

How can I verify the 128 MB cache is active after installation?

Check the drive’s reported cache size in the RAID controller BIOS or with a tool such as smartctl; it should show 128 MB.
