Hi, I have been trying several Ubuntu based distros on a Usb with persistent. I tried Ubuntu 12.04 on 16gb Kingston, and it was slow as molasses. I tried Bodhi, and it wouldn't boot or it would be slow on the 16gb drive. When I use a sandisk 4gb, everything was smooth with Bodhi and fast. It seems anything over 4gb just wont work for me. Tried a PNY 16gb, and the same thing. Is this due to fat 32 only recognizing 4gb ? Are larger Usb pen drives flakey when it comes to running distros persistent etc ?
