are referred to as desktop and enterprise. Enterprise-class SATA disk drives typically cost more and have more features built in to maximize their performance, reliability and availability. There is another tier of SATA disk drives and that involves picking out the best, more reliable disk drives out of a batch of manufactured drives that survive a more extensive test process.

The lower performance of SATA disk drives is a reality in that they are lower cost, so performance enabling technology has been removed. Bottom line is you get what pay for. It is often said that SATA disk drives are the same and that all will be impacted performance-wise when subjected to noise and vibration. This is not a myth, however it really only applies if you subject the disk drives to constant vibration, movement and utilize poor packaging. In other words, don't bolt the disks together with a couple of pieces of scrap metal and place on your desktop surface and subject the drives to extreme random I/Os.
