Can you loose the data on the usb drive ? After the test below you need to recreate the partitions and to re-create the filesystem (formating) again.
All data on destination will be destroyed ! MAKE A BACKUP FIRST !

write test:

Code:

dd if=/dev/zero of=/dev/your-usb-drive-here bs=1024

ah, have I mentioned you will loose all data on your usb drive ?

read test: the read test will not destroy data but it the same applies: MAKE A BACKUP FIRST !

Code:

dd if=/dev/your-usb-drive-here of=/tmp/data.img bs=1024

Those commands might be more useful if the command time was prefixed:

Code:

time dd if=/dev/zero of=/dev/your-usb-drive-here bs=1024

Etc.

dd provides a transfer rate when it terminates

Well I haven't used dd for a long time.
But thanks for the correction
