Here are 2 different 4Gb USB drives. Flash memory: http://www.ecost.com/ecost/shop/detail~dpno~339754.asp $143 Mini Drive: http://www.ecost.com/ecost/shop/detail~dpno~306189.asp $80 How does one load Centos on these? Can you boot from CD, point to an FTP server for OS, and install on the USB drive, eventhough the system has its own harddrive? Does the install have to be for a specific system? Of course right now, I only have one USB bootable laptop. Oh, and ecost is one of the best places to get things like SD memory. Watch their budget countdown...
