As a result of a HDD failure I am upgrading to a RAID1 S-ATA PCI card. I know that RAID1 basically mirrors 2 drives, and if one fails, the other is used. How good is this in practice though? If one fails, and you have to replace 1 drive in the array, is it just a case of taking the bad one out and putting a new one in (of the same size)? In which case, is all the data from the good drive automatically transfered over to the newly installed drive? How is the user made aware of a failure in one of the drives? Also, how does this work if the two mirroed drives have the OS on them and one fails? Will the OS happily transfer over to the newly installed drive in the array?
In addition, can anyone recommend a really good S-ATA RAID1 IDE card? It needs to support 48-bit LBA (HDDs > 137Gb) and bootable array support. It also needs built-in support for first-party DMA to eliminate bottlenecks associated with on-board DMA.
