WD5003AZEX 500GB 7200RPM desktop drive

The Western Digital WD5003AZEX is a 3.5-inch internal hard drive built for desktop computers. It delivers 500GB of storage on a SATA 6.0Gb/s interface with a 7200RPM spindle speed and a 64MB cache. The drive uses dual-core processing, StableTrac and vibration control technologies to maintain consistent performance during daily computing tasks. It ships as a bare drive without mounting screws, cables or documentation.

Suits general desktop workloads

This drive fits users who need a straightforward mechanical disk for operating systems, applications and bulk files on a standard SATA port. Builders who require multiple drives in a vibration-sensitive chassis, or who want the lower latency and silent operation of solid-state storage, should consider a different storage type. The bare-drive packaging also means installers must supply their own mounting hardware and SATA cables.

7200RPM spindle speed with 64MB cache

The combination of a 7200RPM rotational speed and a 64MB buffer determines how quickly the drive can read and write sequential and random data. If your workload demands sustained throughput above what this spindle speed and cache size can provide, a faster storage technology will be necessary.
