Dell EqualLogic 900GB 10K SAS drive

The Dell ST9900805SS is a 900GB 2.5-inch internal hard drive spinning at 10000RPM with a 6Gb/s SAS interface and 32MB cache. It ships new with an R Series caddy for direct installation into compatible EqualLogic arrays. This enterprise-grade unit suits storage administrators expanding capacity in existing Dell EqualLogic SAN environments.

Suits EqualLogic array upgrades

This drive fits administrators maintaining Dell EqualLogic systems that require a 900GB 10K SAS spindle with the supplied R Series tray. Buyers needing a different capacity, a slower spindle speed, or a form factor other than 2.5 inches should look elsewhere. The 32MB buffer and 6Gb/s SAS link match the original EqualLogic specification for this part number.

6Gb/s SAS interface decides fit

The single specification that determines compatibility is the 6Gb/s SAS interface combined with the 2.5-inch form factor and included R Series caddy. Verify the target array accepts this exact SAS signalling rate and physical tray before purchase. No other interface or tray style is supported by this specific part.

Questions about this item

What SAS controller or backplane do I need to run this 6Gb/s ST9900805SS drive?

A controller or backplane with a 6Gb/s SAS interface is required; the drive will negotiate down to 3Gb/s if the host only supports that speed.

Will this 2.5" 10000RPM drive fit in my existing 3.5" drive bay?

The drive is a 2.5" form factor; it needs a 2.5" bay or a 3.5" adapter bracket, which is not included with the unit.

How can I confirm the 32MB cache and 900GB capacity are recognised after installation?

Check the drive properties in your RAID controller BIOS, operating system disk management, or SMART data to verify 900GB capacity and 32MB cache.
