+1 to Sabertooth any day... Seriously seriously wicked board for the money.. worth a lot more actually.
Any specific reason as to the mushkin ? most Sand Force drives will do close to those speeds.. Id pick corsair as well.. much better support in terms of hardware compatibility and stuff.
Think about it.. Corsair tests its ssd's on a crap load of systems.. something a small manufacturer like mushkin is not going to be able to do. Also the corsair support forums are brilliant for any issues at all.
Cheers and kind regards guys !
