(rād) Short for Redundant Array of Independent (or Inexpensive) Disks, a category of disk drives that employ two or more drives in combination for fault tolerance and performance. RAID disk drives are used frequently on servers but aren't generally necessary for personal computers.

There are number of different RAID levels:
# Level 0 -- Striped Disk Array without Fault Tolerance: Provides data striping (spreading out blocks of each file across multiple disk drives) but no redundancy. This improves performance but does not deliver fault tolerance. If one drive fails then all data in the array is lost.
# Level 1 -- Mirroring and Duplexing: Provides disk mirroring. Level 1 provides twice the read transaction rate of single disks and the same write transaction rate as single disks.

the best depends on what you want. Raid 0 gives you the fastest performance, but if one drive gets pooched all your data is gone. Raid 1 mirrors the hdds, so if one drive dies you have a backup of all your data.

edit: for most home users if they make a raid, it is 0 but again, the best depends on what you need/want
