Enterprise SATA drive for server workloads
The Western Digital RE3 WD2502ABYS is a 250GB 3.5" internal hard drive built for business-critical server and storage applications. It runs at 7200 RPM with a 16MB cache and a SATA 3.0Gb/s interface. The bare-drive packaging suits system integrators and IT departments deploying high-reliability storage arrays.
Low-noise operation with vibration tolerance
Technologically advanced acoustics minimise operational noise while cool drive operation supports extended uptime. Fourth-generation RAFF technology monitors and corrects both linear and rotational vibration in real time, delivering up to 60% performance improvement in high-vibration environments. Average seek time is 8.9ms and average latency is 4.2ms.
Dynamic fly-height and burn-in reliability
Third-generation dynamic fly-height adjusts each read-write head in real time for optimum reliability across varying conditions. Every unit undergoes an extended thermal burn-in test before shipment. The low-profile 1.0-inch form factor fits standard 3.5" bays while the dual-processor architecture sustains throughput for demanding workloads.

Questions about this item
How do I install this 3.5" SATA drive and what step is often missed?
Mount the drive in a 3.5" bay, connect the SATA data cable and 15-pin SATA power connector, then enable the port in BIOS so the 250GB volume appears.
What maintenance or replacement will this RE3 drive need later?
No routine maintenance is required; replace the drive if SMART attributes report reallocated sectors or if the 7200 RPM mechanism develops unusual noise.
What limit appears first during sustained use of this 7200 RPM drive?
The SATA 3.0Gb/s interface caps sustained throughput, so long sequential transfers will hit that ceiling before the 16MB cache or mechanical speed becomes the bottleneck.
