3ware give you their drivers for using with their cards ...
7500-2 is the cheapest 3ware cards
7500-4 is for 4 drives
if you only need 2 disks... for the same $$$, you can buy 3-4 40-60GB disk
drives instead and have 3-4 copies of the same thing instead of
one extra copy with to "hardware raid" ( raid1 mirroring presumably )
with only 2 disks
it ain't worth it with 2 disks...
w/ hw raid.. if you erase important-file.txt on your disk, its gone ..
but, if you have 2-4 independent disks with the same $$$ ... you
have as many copies as you want going back years ...
