 |
|
Simply shoving an .mp3 or .avi never seems to determine it's real speed. It's always varying/depending on the size or file type.
How do I perform an accurate speed test?
(Like those ones people include in their SD card reviews on NCIX/Newegg)

It should be the same for all large files of any type, theoretically.
They probably just average.

| What ever the class is, is the max speed. There is no need for a speed test. IF its class 6, it's capped at 6mb/s write speed.

But he wants to know why it doesn't always hit the cap.

Because the device writing to it is crap. my cellphone and 3.0USB do max speed to my micro in my phone. But if I put the micro in an expansion in the old ass card reader I slapped into my rig from an old pc, it hardly hits 3mb/s on a class 6.

Okay, but that still doesn't explain fluctuation on the same device, does it?
Like I have a usb 2 adapter that gives pretty much random rates, is that just the software average calculation borking out?
