But it takes time to access the hard drive. If harddrives and their overhead
were as fast as SDRAM, what would we need the ram for? My 7200rpm drive is
fast alright, but when it's auto-powered-down, i haveto wait 5-10 seconds
for power-up, memory writeout, diskreads, and occasionally that's too long
and something happens. I can't put the rest of the world on hold while the
platters spin up,, especially the firewall logging. It's a pain to be forced
to either keep accessing the hd with dummy requests just to prevent it from
powering down (thereby significantly shortening the drive's MTBF), or
putting the data on a slower drive that won't go into sleep mode.

Kat,
peeved at harddrives that auto-power-down.
