A drive failure in a RAID 0 configuration is effectively a meltdown as this configuration offers no security whatsoever. One drive dies, the entire array is effectively dead and the data is lost.

Your first and foremost task MUST be to back up the data, either through software in Windows or via software such as Norton Ghost or likewise (for outside of Windows cloning), and do this now before it's too late. Then the drive in question will be under warranty so you can send it back for replacement. Then if you've cloned the entire installation with Norton Ghost, set up your RAID again, ghost it back and job's a good'un.

how reliable is raid 0


As Neil Jones said:

One drive dies, the entire array is effectively dead and the data is lost.


Raid 0, (From the OS's point of view) extends two drives into One long Logical drive.
----------------------------------------------------------------------------------------------------
Raid (0+1) is raid 0, with mirroring.
Takes:
2- 500GB drives (looks like a 1TB drive)
2- 500GB drive that will mirror the above 2 drives

If either of the Raid 0 drives fail, the second set will take over. (The mirrors)
----------------------------------------------------------------------------------------------------
Raid 5
Takes 3 500GB drives

Data is being written to all three, in a round robin fashion. along with a parity bit.
If one drive fails, the system keeps going.
---------------------------------------------------------------------------------------------------
The difference between raid 0+1 and raid 5, the amount of discs required and speed.
Raid 5 is a little slower, because it has to write the parity.
---------------------------------------------------------------------------------------------------
If you really want stability and the ability to change the dead drive on the fly.
Raid 5, with hot swap.
Requires:
Hot swap drive cabinet
Hot Swappable Drives.
Requires 3 drives, same as Normal raid 5, plus one for the hot swap.
If a drive fails, system keeps going, and rebuilds the data using the parity information to the hot swap.
Once the hot swap has been rebuilt the dead drive can be removed and replaced,then reconfigured as the new hot swap.


Your MotherBoard supports any of these configurations.

If you have Vista Ultimate you have the ability to back up your system now. Start > All Programs > maintenance > Backup and restore > Create an image (on left side of window)

RAID 0 is NOT RELIABLE AT ALL. Due to the mathematics of failure, you basically quadruple your chance of failure for a marginal at best increase in speed. Synthetic benchmarks show huge increases but real world sees 1-2 seconds or less increase in boot speed and loading of games (most are 1/2 a second or less).

Raid 0 is the worst thing to do because when any drive in the array fails, all data on ALL drives is lost. That's just the way it is. Unless you are running a super large database with multiple drives (not just two) in RAID 0 then it just plain isn't worth it.
