I bought this mainly to help me with my work. This comes in handy when rebooting the operating system on computers with defective CD/DVD drives or on laptops without one. So far I've only encountered one (very old) BIOS that doesn't support the 'boot from' option and I can't blame the drive for that. The drive is very portable and comes with a small dual USB connector in case one connector doesn't provide enough power to run the drive. There is also an external power supply if you come up with your own transformer. I haven't tested the write functions, but that's because I mainly use them to boot new systems.
