Memory Card Zoo SD Test

Adam Ulivi from Memory Card Zoo sent me a Samsung 8Gb micro SDHC class 4.

Memory Card Zoo

Seems like a regular SD card but they claim to be water proof, shock proof and magnet proof.

Memory Card Zoo

I ran a few tests using SD Tools for Android to compare it against the others cards I have around. The result:

The general raw output data collected from SD Tools:

Write Speed (Mb/s) Read speed (Mb/s)
SanDisk Class 4, 8Gb 4.1 11.7
Samsung Class 4, 8Gb 5.5 17.9
Patriot Class 10, 16Gb 8.1 20.1

I use the SanDisk in my Android and Patriot on my camera. It would be a good combo have a waterproof card on my waterproof camera but this sd card can not beat a class 10 card. I may change my cellphone’s memory card for this Samsung.
If you want to try to yourselft this or others models of Micro SD card visit their store. Thank you Adam!
