Speed generates heat
To day, an ordinary "lazy" hard disk rotates at 4500 RPM. The better run at 5400 and the best at 7200, but
there is much development in this area. One of problems is the heat generation, which increases with the
speed. The fewer and smaller platters to turn, the faster they can reach their full speed. Another problem is
noise. I had to return a disk, which turned at 7200 RPM with the sound of a dentist's drill. It was intolerable
to be in the same room!
The best SCSI disks available rotates at 10.000 and 14.000 RPM. They are expensive but ultimately they
provide the highest transfer capacity.
