usb-flash-drive

Suppose I've installed linux on my flash drive. Why do I need something like casper loop file to make saving persistant? So files are being erased? Isn't flash drive the same as actual hard drive? I'm linux noob so be patient. Or it is because linux on flash drive is actually live cd on flash drive? Can it be installed just like it is installed on hard drive?

Thanks in advance
