I need an SD as my old phone has a class 4. I was just wondering how fast is fast enough?

There is class 10, UHS-1 (30-48 meg per sec), and then some extremely fast varients (70-90 meg read speed).

I am eyeing the Samsung branded card that claims 48 meg "transfer" speed in either 32 or 64 gig. I assume transfer means read.

If someone could give me the tech spec as far as what speed the phone is capable of that would be great. I am also very interested in what you are using in your phones and your opinions.

What am I going to actually notice in use with a faster card? Right now all I can think would be affected is the rate at which I can take bursts of pictures.

Thank you in advance. The girls and guys on this forum are the best. Both friendly and knowledgeable. I cant wait to see what I learn from your responses.

That's the one I was looking at. I just don't want to have buyers remorse for not spending the extra for the even faster cards.

I'll prabably just buy that card in 32 gig and hope the redicoluosly large pictures don't fill it up. If they do I can always dump them on my hard drive.

It's another Galaxy. Its predecessors eat cheap cards as bad as the Hero 3. You want like a Sandisk Pro or a Genuine Samsung. Beware Amazon, MANY OF THE LISTED SAMSUNG ARE FAKE.

The one linked says ships from and sold by Amazon. That carries weight for me. I am only wary of non amazon purchases through the amazon site.

I bought the Samsung 32GB EVO at BB last week. What does EVO stand for?

[Relgoshan]

Evo is probably more TLC based flash and also trying to tie into the success of the 840 EVO SSDs. Also from Samsung. I think the more expensive older Genuine Samsung 64GB may be sturdier than the new type, I will look into the speed side of things.

Evo - evolution. But don't worry about those fancy name. Just know that you got a class 10 with 48mb transfer rate! I got one too!

I have done some research on this topic in the last week and it's more complicated than it seems. These cards perform differently based on the size and number of files being written. Tom's hardware did a nice performance test of many sd cards. Without getting to in depth it looks like the Evo card from Samsung is the best overall choice.
