How to Pick a RAID Level For Your Hard Drive
Perhaps you've heard that RAID can be used to increase the performance of your hard drives. Or perhaps you've heard that you can use RAID to increase the reliability of your hard drives. Both of these are possible, thanks to the various ways that you can use RAID in your computer. Some RAID configurations are targeted towards enterprise environments that require the highest fault tolerance (at a high cost), but some of the RAID levels can be used by home users, using inexpensive equipment, to achieve significant gains.The first step to using RAID is to decide which RAID level you want to use. Each RAID level defines a different configuration of how data is read and written to the hard drives and what fault-tolerance features are employed; for example, one RAID level may just provide higher performance while another level will also provide fault tolerance. When it comes to RAID, most of the work is done by an expansion card called a RAID controller; this controller may be a stand-alone card, or it may be built into your computer's motherboard. Many motherboards include a controller that can do either RAID level 0 (also called RAID0) or RAID 1 and possibly a few other RAID levels.
