Hey all, I have another RAID question. I was talking to someone on another forum, and they said that RAID 5 might be better than RAID 0+1. Now, from what I've read, RAID 5 seems to be slightly slower than RAID 0+1, because when reading it has to skip the parity blocks. However, I would have more useable space with RAID 5, and I could also add HDDs, without have to reformat.

My question is, is there a noticable performance decrease with RAID 5 as opposed to RAID 0+1? I was also told that if I do RAID 5 I should get a controller card, rather than use the onboard controller. Unfortunatly, I can't spend $100-300 on a RAID card, so I would have to use the onboard. Would that create a problem of any sort? Basically, which is better, RAID 0+1 or 5?

Thanks!
