Dell 2RR9T 900GB SAS Server Drive

This 900GB 2.5-inch internal hard drive operates at 10000 RPM with a 64MB cache and a 6Gb/s SAS interface. It supports hot-plug installation and is supplied in new condition. The drive is designed for Dell PowerEdge and PowerVault systems.

Suits administrators expanding Dell PowerEdge

IT teams needing a 10000 RPM SAS drive for compatible Dell M-series, R-series or T-series servers can use this part. Buyers whose systems require a different interface or form factor should look elsewhere.

The 6Gb/s SAS interface determines compatibility

Only servers and storage enclosures with a SAS backplane that accepts 2.5-inch hot-plug drives can use this unit. Verify the host controller and bay type before purchase.

Questions about this item

Does the 2.5" SAS drive ship with a tray or caddy for hot-plug installation?

The drive is sold as a bare unit; a compatible hot-plug tray or caddy must be purchased separately for Dell PowerEdge servers.

How do I decide between the 900 GB 10 000 RPM model and a lower-capacity SAS drive?

Choose the 900 GB 10 000 RPM drive when you need maximum capacity and the fastest spindle speed for transaction-heavy workloads on supported PowerEdge and PowerVault systems.

What real-world throughput can I expect from the 6 Gb/s SAS interface in a RAID array?

In a RAID array the 6 Gb/s SAS link typically delivers sustained reads near 200 MB/s per drive, limited by the 10 000 RPM mechanics and 64 MB cache.
