I plan to build a windows 2000 machiene that will work as a file server in my small office. I want to get a motherboard with RAID. I have never used RAID before but is it possible to have the second hard drive (the copy) as a removeable that i can take home at night? if that is possible... will things work normally if i were to rotate every day between two hard drives? so that way if i ever need files from a day ago, i can use that hard drive? will it update the files that need to be updated or will it copy from scratch over again?
