I think it is actually saying that all SLTs can write up to 10mbps (Class 10), but only the A77 & A99 get any additional benefit from the "UHS-1" cards that are 45mbps or 90mbps.

In other words, if you have an A3x, A5x, or A6x, there's no point spending more money to get a UHS-1 memory card or anything faster than Class 10.

My latest card is Sony (94Mb/s) that I use on my a55 and and have noticed it to write faster than older Sandisk 45mbps I'd been using on it. Of course thoe specs represent read speed, but I think the Sony has a faster write speed than the old Sandisk which is noticeable in burst mode.
