250 GB WD RE4 enterprise drive

The Western Digital WD2503ABYX is a 250 GB 3.5 inch SATA hard drive that spins at 7200 RPM and carries a 64 MB cache. It belongs to the WD RE4 product line and is supplied in new condition with zero power-on hours.

Suited for bulk storage and RAID arrays

System builders who need affordable capacity for secondary data, backups or RAID configurations will find the 250 GB size and 7200 RPM speed appropriate. Users who require the low latency and high throughput of a solid-state drive for operating-system boot or active workloads should select a different storage technology.

SATA 3 Gbps interface

The drive connects through a SATA interface rated at 3 Gbps, which determines the maximum host transfer rate. Verify that the target controller or backplane supports this SATA revision before installation.

Questions about this item

What does the 7200 RPM speed mean for daily use in a desktop?

The 7200 RPM spindle gives faster data access than slower drives, so operating system loads, application starts and file copies feel snappier on this 250GB WD RE4 unit.

How does the SATA interface limit real-world throughput?

The drive uses a standard SATA connection, so peak transfer rates are bound by that link rather than the 64 MB cache or 7200 RPM mechanics.

Will this 3.5 inch drive fit in my standard desktop drive bay?

Yes, the 3.5 inch form factor matches ordinary desktop bays and uses regular SATA data and power cables for installation.
