Question: What is the difference between "32GB A" and "32GB B"?
Document: I am amazed so many people are falling for this, did you really think you would get a real 32GB SD card for this much? Even more surprised I'm amazed amazon is letting this scam continue.
I love my generic 32GB class 10 Micro SD it holds a lot of my pictures and folders. So I don't have to delete a lot of my pictures and files nor folders off my phone so I can have space on my phone so I can save other things on it.
This is a fake. They print 32GB Class 10 on it but it is a 1GB card. Read the other 1 Star reviews and you will see.Seriously, read the 1 Star reviews and you will see that it is filled with people who have run an actual speed/capacity test on them - that's the only way to truly know if you got what you paid for.Then read the 5 Star reviews and you will see that none of those people ran any kind of test.
I purchased this card back in October to use in my tablet. I was expecting a 32GB card, but when I opened the package, it turns out I received a 128GB card instead. As you might imagine, I was very happy about that.Unfortunately- and this is the reason I only gave 3 stars- my tablet was not able to read/recognize the card. I chalked it up to the fact that my tablet could only handle up to 32GB external storage.
It works as advertised. Lots of space for a good price. A VERY good price. I can remember when 32K was big and my dad spent $200 for it!
I purchased the generic 32 GB micro HD card for use with my android tablet.I have seen no difference between the performance of this micro HD cardand more expensive brand names. Excellent value.

Answer: a or b really mean nothing. the higher the class 1-10 the faster the transfer rate.
