WD XE SAS enterprise drive

This Western Digital WD XE SAS hard drive delivers 900 GB of storage at 10,000 RPM with a 32 MB cache. The 2.5-inch form factor fits enterprise server and storage bays. The 6 Gb/s SAS interface supports high reliability and scalability for demanding workloads. It is built for power-constrained data centres and transaction processing.

Suits high-performance server builds

This drive suits administrators deploying rack, tower or blade servers that require fast SAS storage in a compact package. It fits environments where space and power are limited but throughput matters. Buyers needing larger capacities or solid-state speeds should consider other options. Systems without a 6 Gb/s SAS controller cannot use this drive.

6 Gb/s SAS interface decides fit

The single specification that determines compatibility is the 6 Gb/s SAS interface. Your server or storage array must provide a matching SAS backplane or controller. Without that connection the drive will not function. Verify the interface before purchase.

Questions about this item

Does the drive include a SAS cable or mounting bracket, or must they be purchased separately?

The drive is supplied as a bare 2.5" unit; SAS cables and any mounting hardware for the target server or array are not included and must be sourced separately.

How do I decide between the 900 GB capacity and other XE capacities for a transaction-heavy workload?

Choose the 900 GB model when you need the maximum space available in the XE line at 10 000 RPM; smaller capacities exist in the same series but offer less room for database logs and scratch space.

What does the 10 000 RPM figure mean for latency when the drive is installed in a 6 Gb/s SAS backplane?

At 10 000 RPM the average rotational latency is roughly 3 ms, so random read and write requests see consistently low access times compared with slower-spinning drives on the same SAS interface.
