I saw your post and was intrigued by your question - I then did the search and found this page.

It would seem the microsdHC just refers to the size of cards i.e. from from 4Gb to 32Gb.
Now as to your request - I have used transcend cards in other equipment - notably a JVC HD 1080p camcorder and their sustained write capability is very very good with no drop out with over 240 hours of HD recordings. So brand wise - it is a very good name and IMHO a good rep.
As to your card running ok with the ace - the fact it is a good branded name and a reasonable size but more importantly a class 10 - then in all probability you will not have any problems.
