Asus P5K Premium Problems + fixes thread

[IanB]

Honestly, I think the only reliable answer with the Premium is to do what you have done (and I am about to upgrade to) - use a hardware RAID card to add RAID capabilities, especially with the latest Samsung drives which are particularly recommendable right now for price/performance.

I'm also far more confident in the results: I am very suspicious of on-board RAID solutions since hearing odd reports of occasional hash errors using QuickPAR that can't easily be accounted for by overclocking or memory issues, but might be a result of poor drivers or an obscure chipset hardware bug. It's probably not an issue with the Intel Southbridge compared to nVidia, but I remain cautious. The other distinct advantages of off-board RAID make it the most sensible solution.

Note that there is a reported bug in the Intel Southbridge (not just on the Premium) restricting maximum bandwidth when connected directly to current SSDs. There has been discussion of this in the News forum.
