Yes I realize there are several questions about this but none of them seem to have the answer I'm looking for.

I have two SSDs and am looking to buy a purely hardware raid card for them; however, I can't seem to find any reviews that have specifically tested hardware raid cards with SSDs rather than testing the SSDs themselves.

I'm looking for a review because I'm assuming that for example: 100% gain with two 7200rpm drives doesn't necessarily mean 100% gain with a pair of SSDs, since there would be higher speeds, meaning more throughput, meaning more processor/memory usage for the card.

If this assumption is wrong then that's fantastic; however if it's true, I am quite sad and would really appreciate any advice or reviews you can find.

Thanks in advance!
