The other day I got a new usb pendrive and want to check the performance, also compared to my other disks. A simple first step is to use dd and write a 1 or 4 or 8 or 128 GB file to that drive. With the following command, you get the MB/s rate of that process.
dd if=/dev/zero of=/tmp/test1.img bs=1G count=1 oflag=dsync
My new USB Pendrive is able to copy with 20 MB/s, it is USB 2.0
