CPUID. Feature: Access Your Computer Anytime and Save Energy with Wake- Booting Linux from Flash - Oopsilon. I like my computers to be as quiet as possible: if a computer is emitting very little sound, that makes it easier to live with. The noise a computer makes is especially important when it's in a home theatre situation, or acting as a media server; if a HTPC is itself throwing out lots of noise, that detracts from the sound of the movie being played. The ideal case, of course, is for there to be no moving parts: things that move or spin inevitably have friction, and that causes noise. I've tried to eliminate everything that spins from my setup: I have a CPU that doesn't need a fan on the heatsink, and a fanless power supply. However, there's one thing left that is spinning, and that's the hard disk which hosts the Linux installation.
Dropping that would make my system truly silent, so I started looking into how that could be done. Unfortunately, it's not quite that easy.
