Few months ago i purchased of ebay some cheap no brand 64 gb sd card that does seem to be working fine but its writing speed is somewhere about 3.4 MB. Then recently i purchased another one at 8 GB just to have it as an installation "USB" which is same class also no brand and it came with same card reader as the first one... But this one actually writes at 11 MB. How come that huge difference ? They are both same class and no branded yet this one is one is almost x4 faster ? Can somebody tell me more about it, i am interested...
