Western Digital RE4 250GB 7200RPM SATA 64MB Cache 3.5-inch internal hard drive

250 GB RE4 for desktop storage

This 3.5-inch internal hard drive provides 250 GB of capacity with a 7200 RPM spindle speed and a 64 MB cache. It uses a SATA 3 Gb/s interface and is sold new in retail or OEM packaging. The RE4 line is designed for desktop workloads that demand consistent throughput.

Build integration and constraints

The drive fits a standard 3.5-inch bay and connects to any SATA port on a motherboard or controller card. It requires a SATA data cable and a SATA power connector from the power supply. The 7200 RPM speed frees up a faster slot for an operating-system drive while this unit handles bulk files. Buyers who need more capacity or a 6 Gb/s link should look elsewhere.
