Warning
- Using a USB drive as RAM will shorten the life of the drive. Flash memory-based USB drives can only be written to a certain number of times. Generally, you can use a USB drive for long periods of time, but if the drive is used as RAM, millions of transfers will be performed, thereby reducing the life of the drive.
- Do not remove the USB drive while in use. Your computer will crash. However, to fix this, all you have to do is reconnect the drive and restart the computer.
