RAID stands for Redudant Array of Inexpensive Disks. It's a hardware specification that allows multiple hard disks to be used as a single volume. In some cases data is written across several disks (striping) or onto separate drives for redundancy (mirroring).
Different RAID levels determine exactly how the disks will be used.
Win2K server supports software level RAID as well (the operating system can be configured so that any data written to drive C: is also written to drive D: for example) but that doesn't affect whatever RAID level the hardware is running behind the scenes.

RAID (Redundant Array of Independent Disks) refers to a data storage scheme using multiple hard drives to share or replicate data among the drives.
The benefit is one or more of increased data integrity, fault-tolerance, throughput or capacity compared to single drives.
RAID combines multiple hard drives into a single logical unit. Thus, instead of seeing several different hard drives, the operating system sees only one. RAID is typically used on server computers, and is usually implemented with identically sized disk drives.
RAID is also being found and offered as an option in more advanced personal computers.
So no need of data to get faulty as RAID provides the solution. Data is continuously backed up on other hard drives and in case of failure the valuable data could be retrieved.
Rest others have already told in their answers.....
For more clarification read any book on "Computers and peripherals"

Windows 2000 Server supports RAID 0 to RAID 5. I think your the question should be what hardware component in your server box to be compatible for which RAID setup.

In computing, the acronym RAID (originally redundant array of inexpensive disks, now also known as redundant array of independent disks) refers to a data storage scheme using multiple hard drives to share or replicate data among the drives. Depending on the version chosen, the benefit of RAID is one or more of increased data integrity, fault-tolerance, throughput or capacity compared to single drives. In its original implementations, its key advantage was the ability to combine multiple low-cost devices using older technology into an array that offered greater capacity, reliability, speed, or a combination of these things, than was affordably available in a single device using the newest technology.
At the very simplest level, RAID combines multiple hard drives into a single logical unit. Thus, instead of seeing several different hard drives, the operating system sees only one. RAID is typically used on server computers, and is usually (but not necessarily) implemented with identically sized disk drives. With decreases in hard drive prices and wider availability of RAID options built into motherboard chipsets, RAID is also being found and offered as an option in more advanced personal computers. This is especially true in computers dedicated to storage-intensive tasks, such as video and audio editing.
The original RAID specification suggested a number of prototype "RAID levels", or combinations of disks. Each had theoretical advantages and disadvantages. Over the years, different implementations of the RAID concept have appeared. Most differ substantially from the original idealized RAID levels, but the numbered names have remained. This can be confusing, since one implementation of RAID 5, for example, can differ substantially from another. RAID 3 and RAID 4 are often confused and even used interchangeably.
The very definition of RAID has been argued over the years. The use of the term redundant leads many to object to RAID 0 being called a RAID at all. Similarly, the change from inexpensive to independent confuses many as to the intended purpose of RAID. There are even some single-disk implementations of the RAID concept. For the purpose of this article, we will say that any system which employs the basic RAID concepts to combine physical disk space for purposes of reliability, capacity, or performance (or even sociability — see the JBOD discussion) is a RAID system.

RAID, it is the way to implent the harddisk to be used in back up, there is RAID 0 and RAID 5 u can read a lot about them in
