Hey guys,
I'm considering going for a three hard drive, RAID5 array along with my next major computer upgrade, because I've had many a failed hard drive! I know more or less how it works, but have a couple of basic questions on it...
1. With onboard RAID controllers that offer RAID5, how heavy are the parity calculations, as I'm guessing they're handled by the CPU? I'm weighing up whether I should consider a separate RAID controller or just use an onboard one.
2. Would my three hard drives then only work with the particular RAID controller that formated/set them up? Just wondering if I could substitute the motherboard/RAID controller if something went wrong, and keep all my data in tact.
3. How does the process of drive reconstruction take place, having replaced a failed drive with a new one? I know in terms of reversing the parity calculations, but does this happen during the POST?
May seem very basic questions, but I'm paranoid about this stuff when it comes to protecting my stuff!!
Cheers
