Or wait maybe that was my Tbolt
I think you are thinking of your Tbolt. The Bionic came with a 16GB micro-sd and 16GB of internal storage. Although you can only actually use 8GB of the 16 for media storage as the other 8 is dedicated to system stuff.
I purchased a 32GB class 4 Transcend card from Amazon for around $30 and have been very pleased with it. Class 10 cards seem to be dropping in price, but their reliability seems to leave a lot to be desired.
