Depending on disk activity, the typical history might cover a few hours to a few days.

RAM was probably also an issue, since selecting each of the options resulted in heavy floppy disk activity.

This is not an issue when there's only moderate disk activity, which apparently encompasses the large majority of my day.

The only difference I could observe was in the amount of hard disk activity I heard.

In general, second launches had a lot less disk activity than first launches.

The bottommost LED on the right side indicated hard disk activity.

But this isn't such a problem since, as already mentioned, most disk activity occurs in multiples of 4096 bytes anyway.

This is done with a low-priority background task, but there's no avoiding the huge amount of disk activity involved.

For example, creating a file, using it for a short period of time, and then deleting it may cause no disk activity at all.

The addition of new "records" to a long report can involve high disk activity and render a system non-responsive.
