Hi Gilboa , Thanks for your qeustion.
I had encountered chapter 26 , which is devoted to linux software raid ,in "Linux(r) Quick Fix Notebook" book By Peter Harrison. (Published by Prentice Hall.) Here is a quote grom the end of this chapter: CONCLUSION Linux software RAID provides redundancy across partitions and hard disks, but it tends to be slower and less reliable than RAID provided by a hardwarebased RAID disk controller.
No advantage what-so-ever
So when you say "No advantage what-so-ever" ,are you referring only when comparing linux raid software to chip IDE RAID cards ? or is your opinion different than Peter Harrison, the book author ? Regards, R. Gordon On 8/16/06, Gilboa Davara <[EMAIL PROTECTED]> wrote:

Which most like means a "soft-BIOS" RAID controller that will most likely have lackluster Linux support (if any) and abysmal performance.

You'll pay more, lose a lot of flexibility (Software RAID can mix different sizes/interfaces/etc) and performance. The only true IDE RAID card that I'm aware of is 3ware 75xx cards. Maybe you can pick one up @ebay. http://www.3ware.com/products/parallel_ata.asp > > Regards, > R.
