Western Digital RE3 250GB SATA Drive
This Western Digital RE3 drive is a 3.5 inch internal hard disk with a 250GB capacity. It spins at 7200 RPM and provides a 16MB cache buffer. The SATA 3.0Gb/s interface connects to desktop systems and servers.
Suits enterprise storage arrays.
The RE3 series targets enterprise environments needing continuous operation and RAID compatibility. Its 3.5 inch form factor requires a standard drive bay and desktop power. Buyers needing laptop drives or external portable storage should look elsewhere.
SATA 3.0Gb/s interface determines compatibility
The drive uses a SATA 3.0Gb/s interface with a 7-pin data connector. This specification decides whether the drive fits the host controller or backplane. Verify the system supports this interface generation before purchase.

Questions about this item
Will the 1.0 inch height and 25.4mm maximum height fit my 3.5 inch drive bay?
Yes, the 1.0 inch low profile design matches the 25.4mm maximum height specification, fitting standard 3.5 inch internal drive bays.
How do I connect the SATA 3.0Gb/s interface correctly, and what is the common mistake?
Connect the 7-pin SATA data cable and 15-pin SATA power cable firmly; the common mistake is leaving the data cable loose, causing detection failures.
When should I expect to replace the 250GB drive given its 7200 RPM speed and enterprise RE3 design?
Enterprise RE3 drives are built for continuous operation; monitor SMART attributes for reallocated sectors or seek errors as replacement indicators.
