SATA RAID Drives
Recently deployed a new system - Athlon 2500 with ABIT NF7-S Mobo and 2 X Western Digital 80Gb disks set up as SATA mirrored RAID drives. OS is Win 2000.
The reasoning behind the RAID drives is that I simply cannot afford to lose data, or waste time on retrieving files if it all falls down.
The RAID drives have already saved my bacon once - Windows announced that a vital system file was missing - and refused to load. Swapping the drives and mirroring them again sorted that out, but led me to wonder just how safe I am - what happens, for instance, if a virus gets through in my e-mail - how quickly are any infected files going to get mirrored to the other drive?
So what I'm asking is exactly how does RAID copy files to the mirrored drive, and when and how often does it update the second drive?
Alternatively, can anyone point me to a site that explains the underlying mechanisms?
