Consider browsers like Chrome that will write to your disk while you are browsing in order to store the current session. This will in normal use only result in writes to the disk, but no reads at all, allowing you to spin down the drive.

The session data involves a few things, including a cache. The on-disk cache is read many times, especially when you go to another web-page on a site you are visiting. You are also forgetting all the other things that need to read your disk, like Chrome loading all the dynamic libraries (you may not have everything loaded into RAM at that time), and the rest of your OS.

For safety, I doubt the kernel would allow a device to spin down while there are dirty pages for that disk anyway.
