I don't know if this is the correct list (sorry if not), anyway: I need to implement a simple raid1 with 2 9gigs SCSI HDD. I need a inexpensive solution ... so i was thinking about a software raid1. Is it possible? is it too slow?
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.
The question was about RAID-1 (mirroring), which is more related to availability than performance. You only need additional disks if you need more than one disk's worth of data.
