Your really not going to see very good performance with RAID if you're using only two spindles (i.e., discs). You might want to try going with 4 4G discs, if possible. The question of performance is directly related to exactly how much I/O you're going to be shoving through the discs. "Only a mail server" doesn't really provide enough information, IMHO. > How can i do hw raid with a low cost card?? and.. what card?
