micro sd class importance?

[martynsimo]

Im looking to buy a new 16gb micro sd card for my new desire hd. Do any of you have a class 10 card? Does the better class cards improve speed of games/ apps loading up. Is the price worth it? Cheers

It isn't really worth the extra cost, all it is supposed to guarantee is minimum transfer rates.

As such, a class 4 card could have a peak transfer rate matching that of a class 6.

The class system is unreliable at best too with loads of cards not matching the required speeds. Basically ignore the class number and buy a brand you trust, that's basically all you can do

I bought a Sandisk class 6 and the difference over my Sandisk class 2 cards is amazing. Both report correct transfer rates in the SD card tester app and the class 6 is 3 times as fast. Using the gallery is greatly improved and because I used a2sd+ the loading of apps is much quicker as well. So I completely disagree with the posts above - just check the I/O differences of a few cards and the difference is obvious. I would say buy a brand you trust (from a reputable source) and the speed will match the class on the card. I imagine the people above have bought cheap Chinese fakes or something.

I assume the OP has seen that hot deal on a 16gb class 10 card that is going around? I'm thinking of getting one as well.

EDIT: Actually I'm probably being a bit hard on krooton there, some lower class cards are known to transfer higher than their rating suggests but it's by no means a given as all my class 2 Sandisks only transfer 2MB/s whereas my 6 is 6MB/s. Best way is to test the speed and if you're only getting 2MB/s then a class 10 will be a big improvement, assuming the card is for real.

Thats the key phrase there i think - 'assuming the card is for real'

I would feel happier with a quality class 2, than a cheap class 8 that cost me a fiver from Hong Kong via some auction.

I've just seen a Lexar branded 32gb class 10 for 40 quid. Anyone know if these are any good?

Just switched from an N900 to an HTC Desire Z. Nice phone but I miss the 32gb storage of the N900. Can the Desire Z even use a 32gb card?
