RAID 0 and RAID 1 [modified]
-
I am about to buy a new computer and is having some problems. I have no experience at all on RAID. From what I understand, RAID 0 increase performance since two disk are sharing the work load. RAID 1 is reduce the risk of disk failure. However, I have some questions? 1.) If I buy a pc with RAID 0, later, can I change it to RAID 1? Is it just a matter of setting jumpers? 2.) For RAID 1 config, if one drive fail, do I get any notification in such failure(so that I know it had failed)? How do I get my data back from the working drive? 3.) This is unrelated, but anyone know the difference between the Pentium D process and the Core 2 processor? Core 2 cost more, I assume it is better? Thanks in advance:) -- modified at 16:21 Monday 25th September, 2006

Backup all your data, re-build the RAID array as RAID1 (this will delete everything from the drives), restore the system from backups. No jumper settings are used, just software.

You should get a monitoring program with the RAID controller that tells you about drive failures. Replace the failed drive with a wworking one and the array will be restored automatically.
