I bought SanDisk Ultra 32GB Class 10 UHS 1 Micro SD and im only getting a MAX speed of 8.9 MB/s
but on average is 6 MB/s to 7 MB/s .
I bought this card for my GoPro Hero 3 Black and i know it needs above 10 MB/s to record Full HD.
I have used H2testw, Crystal Disk Mark, on windows 7 (High spec) USB 3 port with USB Card reader
I have used SDspeed App and Black Magic Speed test App on an 27" iMac (2012) Built in Card Reader
On both computers and with all 4 Programs, i get the same results. have a done something wrong ?
am i testing it wrong or is my card that slow ?
It was bought from http://www.gizzmoheaven.com
i have no reason to think its fake from there… Or atleast i hope not.
it came sealed in cardboard packaging and looked genuine.
i have included a screenshot
