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.

Richard Falk (Customer Support) Says:
The magnetic platter hard drives are great it you need storage as their price per GB is MUCH better than an SSD. For a primary drive however, I recommend an SSD as typically platter drives have Random Read 4KB performance of less than 300 IOPS while most standard SSDs have better than 94,000 IOPS, What this means is that with an SSD, you will have much, much faster boot times and program loads if you use an SSD as your primary drive.

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.
