I have a RAID10 setup on my PC with 4 x 150Gb Raptors producing about 240Gb of C: Drive space - its been brilliant right from the off!

My second HDD is again an Adaptec RAID0 with 2 x 750Gb WD's which I use as one of my backups of ALL my data on the C Drive.

I really need to enlarge the array of my C Drive to 1TB - can I simply replace each drive (one by one) and let the Adaptec Card rebuild automatically as I replace each drive - would that work or do I have to reinstall everything?

If I have to reinstall - I probably will not bother - I will just use the second HDD Array I have in my PC for storage etc and use the RAID10 for OS & Programmes etc

I don't believe the adapter would cope with replacing the drives in the array with completely different ones, you'd probably end up with a 240G or so RAID across 4 1TB drives, the rest unused :)

Using RAID0 for a backup is very strange, that's half as resilient as a regular drive. Especially as you have 1.5T in the backup and only 240G in the array being backed up!

I would suggest a reinstall, but you could reuse your existing 750G drives as part of your new array, buy two more and RAID10 them again?
 
Some cars will let you expand an array once it is built. It may not though! All depends on the card.

A RAID0 is very very silly for backups. RAID1 isn't really reliable for your only backup but RAID0 is a bad choice!
 
As above...

But if you're not looking to change hardware I'd RAID0 the Raptors for OS/Apps/Games though 4x150gb is probably a bit big and then RAID1 the 750gb drives for data so you have some resilience for important stuff.
 
oh and when I do a backup - its automatically backed up on another PC (our server) in the garage on a 1TB RAID1 (mirrored) array too AT THE SAME TIME!
