RAID
Configuring two or more hard drives in a RAID setup can speed up hard-drive performance and provide automatic protection against data loss from a drive failure. RAID used to be expensive, hard to implement, and limited to businesses with dedicated IT departments, but now even the motherboards on most budget PCs support it, making RAID easier to install and well within the price range of most tech-savvy PC users.
