The WD6400AAKS 640GB Western Digital hard drive quickly earned a reputation for performance and reliability in its day, and the unit I recently won on eBay has lived up to this. Benchmark results come very close to current WD drives' performance levels despite this drive's relatively small 16MB cache, making it a good choice for most any storage duty. I currently use this drive in an external dock to serve up a number of VMware Virtual Machines. These VMs used to reside on a Western Digital 1TB Caviar Black, which is also known for high performance, and performance is comparable. Since this drive was used, I ran a detailed sector analysis and a full (not quick) format to ensure any weak sections were properly identified. The drive has now been in service for a number of weeks with no issues.Read full review
