Which card should I get? I dont really need 32GB; 16GB is enough. I dont shoot video often, and those I do are only a couple of minutes.I see some comments state class10 is different among brands. How's that possibleif manufacturers have to comply with the specs? Is there a way to test if the card is truly class10?
Well, the first one offers lifetime warranty. Class 10 means it should at least be able to write at 10MB/sec.
If 16GB is enough, I'd say both of them are fine Be sure to post a benchmark once you've got it. It can help others picking their card!
I can recommend you Sandisk. Buy a brand instead of noname. You get more speed and reliability wich is the most important thing
Sandisk, Sony or Kingston all are best brands of memory cards.
One good rule of thumb is to look for a manufacturer statement of actual read and write speeds. Absent that, assume its a snail. You're right that a Class 10 rating means almost nothing.
And donÂ´t buy via eBay or any unknown sellers: I bought 3 Kingstons via eBay and they all failed within a few months!
I buy a lot of things from ebay & usually do OK but I agree with dean on this.The one card I bought on ebay was a 32GB MicroSD turned out it would only hold 8GB maybe. When I tried to put more data than that it would erase some of the data it already had on it. So I didn't trust it with any data. My opinion is it is a fake.

As some people suggested above, first look for the official read/write speeds for the card. Also, go for SanDisk, Kingston or some reputed brand, but its your own choice. Hope it helps.
