Well, not a million times, but certainly headed that way. http://www.deja.com/home_ps.shtml enter *freebsd* in the forums (groups) and enter the keywords RAID >1.

No Adaptec RAID support. Try a Mylex DAC 960 based card for low end or the AMI MegaRAID. Its pretty straightforward to setup via the card's BIOS. > >2. Which will give me better performance?

In the limited testing I have done with my controller, there wasnt a hell of a lot of difference between RAID0 and RAID 5. But you really should search through the archives. There are many posts. ---Mike Mike Tancsa (mdtancsa@sentex.net) Sentex Communications Corp, Waterloo, Ontario, Canada "Given enough time, 100 monkeys on 100 routers could setup a national IP network."
