question... I'm thinking about buying a hardware RAID controller for my desktop. The main reason I don't want to go with software RAID is that my mobo IDE controllers are allready full with other stuff, and one of them may have a problem. So, I would need some kind of controller anyway.

I'm not doing it for performance, just for reliability. Yeah, I have additional backup, but I like the idea that the data will be accessible even if a disk crashes. So, that's main priority.

Are you looking for SATA RAID or IDE RAID?

If IDE is your thing, the undisputed king is 3ware (www.3ware.com). I've been reading about 3ware controllers on the forums and mailing lists for the last two or three years now, and I have yet to come across one negative remark.

If you're looking for SATA, again, 3ware has some nice products. There is another option though, Areca (www.areca.com). The performance of these cards are awesome, their features and management options leave you wanting for nothing. Have a look at this: http://www.tweakers.net/reviews/557/1

I have been bashing my head against the wall thanks to a LSI Megaraid card that's supposed to be hardware raid but gives me 6MB/s write performance to a 4 disc RAID-5. If the replacement for this card from the supplier don't fix the problems, I have arranged with the local Areca supplier to take my server there and give it a try. Will report back if it's good.

In the mean time there is a thread on the debian-isp list about that, and one user gave some useful performance info on the areca card.
