Not so. Considering that most modern disks (at least most modern midrange to highend disks) have 256 kB or 512 kB caches, any application which writes data in short bursts (short enough to fit in the cache) is going to benefit from this. 'make buildworld' comes to mind; although the overall output is probably not enough to swamp the disk, most of it happens in small bursts of a couple of tens of kilobytes. -- Noone else has a .sig like this one.
