For boxstar I was thinking of having the live buffer in RAM to save
writing to the HD, and even wondered about having it in the player
front-end instead of the server. Both approaches have their pros and

The beauty of virtual memory is that it works both ways. An application
written to use a file can have the file cached in RAM and one written to
use RAM can have it swapped to disc if the RAM is needed for something

But I wonder, does writing to the HD really shorten its life
significantly compared to constant spinning or frequently being spun up
and down?
