Dell 900GB 10K SAS Internal Drive

The Dell 9XS066-251 is a new 900GB internal hard drive spinning at 10000RPM. It uses a 2.5 inch SAS 6Gb/s interface and includes a 64MB buffer. The drive ships with an R Series caddy for installation in compatible Dell systems.

Suited For SAS 2.5 Inch Bays

This drive fits servers and workstations that accept 2.5 inch SAS drives running at 6Gb/s. It is not for systems that only support larger 3.5 inch form factors. Buyers needing a different interface protocol or larger physical size should look at other parts.

6Gb/s SAS Interface Decides Fit

The single specification that determines compatibility is the 6Gb/s SAS interface. The host controller and backplane must support this exact connection standard. Verify the system requires a 2.5 inch SAS drive before purchase.

Questions about this item

Which capacity and speed combination should I choose for this Dell 2.5-inch SAS drive?

The drive is supplied as a single 900GB model spinning at 10000RPM with a 64MB cache, so there are no alternative capacities or speeds to select for this part number.

What does the 10000RPM spindle speed mean for actual performance in a server?

A 10000RPM spindle reduces average rotational latency, giving faster random read and write response than slower-spinning drives, which benefits transaction-heavy workloads such as databases or virtualisation.

How does the SAS 6Gb/s interface limit real-world throughput?

The 6Gb/s SAS link sets the maximum bus bandwidth, so sustained sequential transfers cannot exceed the interface ceiling, while the 10000RPM mechanics and 64MB cache determine actual read and write speeds within that limit.
