Re: New Mailserver...

[randall <randall@songshu.org>]

i think you have a 1000 options here, but here is basically what i do

the new barracude 7200.11 or es.2 disks are pretty competitive compared 
to the raptors in performance, and they also give you a lot more space 
for your Euro. (250GB for 74 Euro a piece) i personnally use 4 x 500GB 
in a RAID6 (about 100 something a piece)
you might consider dropping the raid controller and go with linux 
software raid instead, altough the software raid will give you less 
performance, but you can sort of compensate this by spending an extra 
100 or 200 on your processor instead (i use the q6600)

besides personal preference and insight, you might want to re consider 
the software vs hardware raid, i just find the kernel more reliable and 
forgiving then any controller.
