Guillaume,

When you configure your target as a compressed (or uncompressed) ramdisk, the entire root
file system is copied to RAM after booting the kernel.  In other words, the target device
(floppy, flash, etc) is used only for booting.  All the files on your system exist in RAM,
so if you make changes to any of the files, they won't survive a power fail.

Having the file system entirely in RAM is a good thing for embedded systems.  It the
system loses power, file system corruption is not an issue because everything will be
restored from the target device on the next boot.

Your system should not run noticeably slower, but be aware that power failures could cause
the file system on your hard drive to have errors.

Depending on what exactly you are trying to do, it might be best to try to find some more
RAM for the PC.
