SD Card Speed/Compatibility

[jimmiekain]

Ok maybe im getting a little ahead of myself since i dont even have the phone yet but I'm already buying accessories for my sprint touch pro 2. Here is my question:

I searched high and low and I cant find it but a month ago or so i read a thread on here where someone posted a link to buy a 64gb micro sd card then in some of the posts under a few people said it was nice but that it wouldn't work in pocket pc's I dont know why! Just know a few of you said that... well I'm looking for a good 8 or 16gb micro sd for my touch pro 2 (when it gets here) but I'm afraid it wont work... How do i know what micro sd's are compatible for our phones? Also are any of them any faster than others? Like will buying an expensive name brand resulting in faster reading or writing to the card? Can anyone make a recomendation?
