Are there stats to backup the fact that linux software raid is faster than the highpoint chips+linux software raid - I have not seen any articals to that effect - except that there are efforts to make the software raid work with the chips which seems to idicate there are advantages involved? My only experiance is on a winme (or was it 2000) system which was noticably faster on disk access for streaming audio work (recording) when running raid 0 (the other raid options are irrelevant to most "home" users I would think, speed being the priority - they may be fake but it appears to work well under windoze, why not linux?) - which was my aim when I purchased the board. RedHat have done some work and offer a kernel patch so my options at this stage appear to be to try and roll my own kernel using the redhat patches onto the Mandrake sources, after which to move to the redhat kernel. I am not sure but I think these patches are now in the RH7.2 kernel and have been subitted for the mainstream kernel, which may solve the problem eventually.
