LSI 9260 vs. AMD SB850

[Computurd]

"free" fake raid shouldn't be outperforming 9260

with only two devices it might outperform it in some scenarios. but not in stability of course. a few bluescreens and your array is a goner on most fakeraids.
however, you shouldnt be buying a 500 raid card for two devices anyway. this is for larger arrays, where the ICH or SB850 couldn't even begin to keep up.
also, i couldnt help but notice that you are comparing a soft raid to a real raid. any type of software raid will be faster, while also being inherently unstable, and chew your cpu resources up as well.
that doesnt seem to be a fair representation. the 9260 is designed for uber throughput, with large arrays for specific use in enterprise environments, and supercomputing. it is tuned for large arrays and scales beautifully with them.
for low latency usage they have the fastpath key, which will tear up anything that you put it up against.

Note the latency with re-badged A-Data SF1222 drives.

havent heard good things about that set of drives. seems to be knock-offish with poor firmware support.
