AFAIK, the spinning down of IDE disks is done by the disks themselves
rather than by the kernel. The software support consists of a method to
tell the disk controller what idle period to wait before spinning down.

I don't know whether SCSI disks have a similar feature. But if they did it
would be easier to make use of that than to implemement a software
timer...
