I did a test with Xbench (a free online app to test drive speed) here are the results (check file attached). Am I reading that right? Is about half the speed it should be?
Here is my post in the apple forums on this subject:
I did a little (ok well maybe a lot) research. Here was the solution...I went into 'disk utilities' and reformatted my flash drive from MS-DOS to Mac OS...bam! done. The drive is about half as fast at the read and write speeds but much faster then before I reformatted. I transfered my entire iphoto library (44.7 GB, 10,756 files including 165 videos) here are the numbers:
Transfer from iMac to flash drive: 22 minutes - before reformatting: 1 hour 44 minutes!!! and yes USB 3.0 !!!
Transfer from flash drive back to iMac: 8 minutes 30 seconds
