Hacking What's the difference between the sd card classes?

[smudgydonkey]

Do games run smoother? I was also wondering whether it really mattered if I get a class 2or 4 since Best Buy doesn't seem to stock class 4 cards that aren't PNY.

The class of a card generally means how fast the constant read/write speed is, but it also can effect response time.

I'd go with a Class 4 or better. Class 2 may be too slow for some games.

Also, keep in mind that some brand's Class 2 cards may be faster than some Class 4's. Eg: My Sandisk C2 is faster than my Kingston C4.

Great place to get cards is newegg.com, you should check it out.

I got a class 4 kingston 4gb and it is generally faster.

class x means read/write minimum afaik. Although it might be possible some cards are faster than indicated, it's rather unlikely. Class 4 seems to be the best (some class 6 have been seen to actually induce problems). That said, I've a Class 6 Transcend (brand, so not just SD

) 8GB ... no problems found.

Oh yeah, brand of card still says more than an indication ... browse around for names, I think Kingston (Taiwan, or was it Japan?) and Transcend were usually the better ones I think. Haven't been looking for a while though, best is to check other flash-card brands and see with which they have trouble with ...

still testing Class 2 pqi microSD 4GB HC. Am using Kingston 4 and 8GB.

class 2 are no-no for me from now on even though they are fast as you said. I prefer class 4 or 6

There ya go, for anyone who needs or would like to know CLASSES EXPLAINED. If you just simply Scroll Up you'll find speed which explains it, hope that helps

Well you would say that wouldnt you as you are expecting a nice fast sandisk 8gig ultra class 6 soon(Sad as i only have the 4gig version)

I must say though that sandisk are a very solid relable card and my ultra class 6 runs smooth with no problems

* Class 2: 2 MB/s - 13x
* Class 4: 4 MB/s - 26x
* Class 6: 6 MB/s - 40x

Kingston's should be reliable.

Sandisk and Kingston are both awesome. (i have one of both)
