All SanDisk USB Flash Drives

My 64GB SanDisk UltraBackup seems extremely slow, taking over two minutes to copy a single 1GB file. Is this normal?

I have verified that the drive is plugged into a USB 2.0 port, so it's not that.

that sounds about right. to be sure download ATTO benchmarking tool and post the results here

I used that program and I have 5MB write and 25MB read access. This seems slower than benchmarked in the previous link. Any suggestions?

Thanks for the link. I have 5 different thumb drives of various sizes from various manufacturers, and their results seem to confirm what I'm finding with my own drives.
