SpeedOut lets you know USB Drive Speeds

[Alboguy]

USB drives have their own read and write speeds and based on this speed you can use it for specific purposes like playing a game directly from the drive etc. SpeedOut is a simple freeware tool which tells you about the read and write speeds of your USB drive. The application is completely portable and does the testing of reading and writing into the drive before arriving at the actual speed of your USB drives.

That's real helpful as some are MUCH faster than others.
Is it true, that after many, many erasings, the stick develops errors and/or slows down?
