Puppy Linux 5.10 desktop running in RAM

This is a list of Linux distributions that can be run entirely from the computer's RAM. That ability allows them to be very fast, since reading and writing data from/to RAM is much faster than on a hard disk drive. Many of these operating systems will load from a removable media such as a Live CD or a Live USB stick. A "frugal" install can also often be completed, allowing boot up from a hard disk drive instead.

This feature is implemented in live-initramfs and allows the user to run a live distro that does not run from ram by default by adding toram to the kernel boot parameters.[1]

Additionally some distributions can be configured to run from RAM, such as Ubuntu using the toram option included in the Casper scripts.[2]
