Desktop RE3 hard drive

The Western Digital RE3 WD3202ABYS is a 3.5 inch SATA hard drive built for desktop systems that need dependable storage in continuous operation. Its enterprise-class manufacturing targets 24x7 duty cycles with a rated mean time between failure of one million hours.

320 GB capacity at 7200 RPM

The drive stores 320 GB on platters spinning at 7200 RPM with a 16 MB buffer and a SATA 3 Gb/s interface. That capacity and speed combination decides whether the drive matches the storage space and throughput a build requires.

The 3.5 inch form factor mounts in any desktop drive bay using regular SATA data and power cables. It leaves smaller 2.5 inch bays free for solid-state drives and adds no special cooling or controller requirements.

Questions about this item

How much usable space will the 320 GB drive show in the operating system?

The manufacturer labels the drive as 320 GB; the operating system calculates capacity differently so the reported figure will be lower.

What does the SATA 3 Gb/s interface limit in real use?

The SATA 3 Gb/s link caps the maximum burst transfer rate at 3 Gb/s; sustained throughput is limited by the 7200 RPM platters and 16 MB cache.

Will this 3.5 inch drive fit a standard desktop drive bay?

Yes, it uses the standard 3.5 inch form factor and SATA connectors, so it mounts in any desktop bay designed for 3.5 inch SATA drives.
