No cache isnt a big loss, Still will yield way better performance over intel raid setup wether it be hardware or software raid.. You can go for the 9211 but i believe doesnt support raid 10 or raid 5, cant quite remember tbh.. 9240 would be your best bet with a FP key.. @ tiro im quite sure it increases IOPS mate, seen a thread a while back from one of the ssd gurus..
