Ubuntu – Running Ubuntu off USB 3.0 flash drive


What is the minimal size USB 3.0 flash drive that I would need to run Ubuntu.
Would it be as fast as running it of the hard drive?
Would it have access to all of my laptops facilities?
I am thinking of investing in a 64 GB USB 3.0 flash drive to run Ubuntu off rather than bothering with a separate partition> DOES THIS MAKE SENSE?

Best Answer

For a Full install of Ubuntu 12.04, and above, minimum disk space recommended is 5GB.

Ultimate speed depends on the make and model of the flash drive. Some USB3 flash drives are faster than others.

Your solution makes sense to me. Your laptop should see it as just another drive.

Probably a good idea to encrypt the drive and home folder as flash drives can be easily misplaced.
