250GB Enterprise SATA Drive

The Western Digital RE3 WD2502ABYS-18B7A0 is a 250GB 3.5-inch internal hard drive built for business-critical workloads. It spins at 7200RPM with a 16MB buffer and connects through a SATA 3Gb/s interface. The drive is supplied new and includes enterprise-class reliability features for continuous operation.

Suited for RAID and server storage

This drive fits administrators expanding legacy SATA arrays or replacing failed units in existing RE3 deployments. Its 250GB capacity and enterprise firmware target multi-drive environments where vibration tolerance and consistent throughput matter. Builders needing larger single volumes or modern 6Gb/s SATA throughput will not find those specifications here.

SATA 3Gb/s interface decides compatibility

The 3Gb/s SATA link sets the maximum host transfer rate and determines whether the drive matches your backplane or controller. Verify that your system supports this generation before purchase, as newer 6Gb/s ports will negotiate down to the drive's rated speed.

Questions about this item

What does the 250GB capacity mean for this WD RE3 drive?

It provides 250GB of storage for operating systems, applications and data on a desktop or server.

How does the 7200RPM speed affect real-world use?

The 7200RPM spindle delivers faster sequential reads and writes than slower desktop drives, suited for business-critical workloads.

What does the SATA 3Gb/s interface limit in practice?

The SATA 3Gb/s link caps maximum transfer rates at 3Gb/s, so sustained throughput will not exceed that ceiling.
