Western Digital RE2 250GB SATA Drive

This Western Digital RE2 desktop internal hard drive delivers 250GB of storage on a 3.5-inch form factor with a SATA 3.0Gb/s interface. It spins at 7200 RPM and includes a 16MB cache for responsive data access. The bare-drive packaging suits system integrators and enthusiasts building or upgrading desktop PCs. It targets users who need reliable mechanical storage for everyday computing tasks.

Thermals Noise and Power in Normal Use

The 7200 RPM spindle speed produces typical mechanical drive acoustics and heat output for a desktop environment. Power draw follows standard SATA 3.0Gb/s device levels during active reads, writes and idle periods. No specialised cooling beyond normal case airflow is required for this drive. Operate within the manufacturer's specified temperature range for consistent performance.

Build Integration Requirements

The drive fits any standard 3.5-inch internal bay and connects via a single SATA data cable and SATA power connector from the power supply. It frees up M.2 slots for solid-state boot drives while adding bulk capacity for files and applications. The bare-drive package means mounting screws and cables are sourced separately. Builders needing higher capacities or faster interfaces should consider other options.

Questions about this item

How do I install the WD2502ABYS-02B7-20PK 3.5" drive and what step is often missed?

Mount the bare drive in a 3.5" bay using four screws, connect the SATA data and power cables, then initialise the 250GB volume in Disk Management — the step often missed is creating a partition before formatting.

What maintenance or replacement will the RE2 drive need later?

The 7200 RPM mechanical drive has no user-serviceable parts; plan to replace the unit if SMART attributes report reallocated sectors or if the 16MB cache cannot mask read latency.

What limit appears first on the WD2502ABYS during sustained writes?

The 3.0Gb/s SATA link and 7200 RPM platters cap sustained transfer rates, so throughput plateaus at the interface ceiling before the 16MB cache fills.
