I think you misunderstood Paul's explanation. Setting the anti-skip
buffer to 5 seconds doesn't mean that the buffer is refilled every 5
seconds. It means that the buffer is refilled 5 seconds before the music
would stop. In general, you want to have zero anti-skip buffer, i.e.
spin up the disk as late as possible before running out of buffered
data. The anti-skip buffer is the safety margin you have in this case
(for the price of battery life of course).

This is not a good idea if you want to get decent runtime. Actually I
don't know why anybody would want to have an anti-skip buffer of 10 mins.
