I just discovered some of the U3 rated micro SD Memory cards out there are improperly (over)rated. This can cause video drop outs or other odd camera or video file issues.


There are free programs you can download to check your chips. I posted a few links under the YouTube video description if interested (view on YouTube site for those).

His premise is flawed... The write speed (and read speed for that matter) on the packaging and advertising are the peak write (or read) speed... it is in fact very typical for the sustained write speed to be a third of that... right in line with the readings he got. All of this is same in any technology... real life results vs. specs.

OTOH, there are a lot of “off brands” out there that mis state card capacities, at times significantly.

Dustoff... I'm curious what brand and version cards you've got, and what your test numbers were like. Looks like I'm going to have to replace mine. Thanks
