Background on Hard Disk Drives

Traditional hard drives operate by storing data on one or more spinning metal disks, called platters. The more platters there are in a drive, and the more data that can be crammed onto each platter, is what determines the overall storage capacity of a given hard drive. Having more platters also tends to mean louder drives, though rotational speed affects that as well. Rotational speed also impacts the drive's performance: if platters spin faster the drive can reach data in different areas more quickly and read or write more information per second.

The alternative to hard drives is solid state drives, which are many times faster but much more expensive for the same amount of capacity. The price gap is dropping over time, so SSDs are becoming more and more preferred for us. For performance, reliability, and noise reduction, SSDs are really the way to go.


Western Digital's Blue drives are both cost effective and relatively fast, as hard drives go, thanks to the 32MB onboard cache and high-density platter technology. This makes it an acceptable primary drive for computers when cost is a major concern, though for most users a solid-state drive will give far better performance without too much of an increase in system price.

This update to the 500GB model boosts read and write speeds, and slightly decreases seek noise.
