What is boinc doing that would require the hard drive to spin so fast? Hard drive spins at the speed it was designed to. Never faster or slower. Do you mean the cooling fan(s)? The more things the computer does, the more it needs to be kept cool. ID: 92565 ·

We could also read "hard drive to spin so fast" as a synonym for "hard drive to spin so often" - in other words, lots of activity shown by the hard disk activity LED. In that case, the answer would be 'checkpointing' - writing intermediate result data to disk, so that if processing is interrupted for any reason, it can re re-started from somewhere close to the point previously reached. That can save a tremendous amount of wasted computation on long tasks. ID: 92566 ·
