7 That's why I mentioned laptop-mode-tools. If configured properly, it
8 ensures that the drive will not spin up a few seconds after having
9 stopped, by buffering all writes. For example, I have configured my
10 laptop to buffer writes for up to 10 minutes.

12 The drawback, obviously, is that I can loose up to 10 minutes of work if
13 I have a power interruption, but on a laptop, this never happens. I'm
14 not sure I would want to have that on a server, though.
