SD Card


i am curious... has anyone claimed warranty on a faulty 3 year old SD card before?

Yes, I had. Claimed a 16G micro SDHC from Sandisk (Peninsular Plaza?). 5 years warranty. No problem. You need the receipt. Lucky I bought from Challenger, and got it to print out a spare receipt. They checked it, and gave me a new one.

Micro SD like easily spoil... more so than SD.
 

Not all class 10 are the same. SanDisk Extreme class 10 are said to be one of the fastest.

In my opinion, K5 cannot take advantage of 90Mb/s using UHS-I.
So should take Class10 45MB/s, it's enough.
I've just bought Sandisk Extreme 16GB Class10 45MB/s, and really satisfied. It's much faster than my previous Class4.
