So I got my 16GB 1000X Lexar Pro cards, and decided to run a little test vs. my 400X SD cards (both are 16GB).
I used my Kingston USB 2 reader and my Kingston USB 3 reader for each card, and timed the transfer of 2.03GB of JPEG files.
Here were the Results:
400X SD from USB 2.0 Reader: 2:31.8
1000X CD from USB 2.0 Reader: 1:10.7
400X SD from USB 3.0 Reader: 2:05.4
1000X CF from USB 3.0 Reader: 1:09.1
So 1000X is a big benefit vs. the SD card, right? Then I put the 400X SD-card into the built-in reader in my ThinkPad T430s...
It took 59.1 seconds. Ten seconds FASTER than the 1000X card!
After each test, I wiped what I'd copied so the remaining space on the drive was the same.
I'm trying to figure out why, but I thought some here might be interested and have some insight.
