but does the OS on its own really need a significant amount of I/O access to the disk? I would guess not.
Generally not.

faxcron
FAXCRON(8) System Manager's Manual FAXCRON(8)
NAME
faxcron - HylaFAX routine maintenance script
SYNOPSIS
/usr/sbin/faxcron [ -n ] [ -l lastrun ]
DESCRIPTION
faxcron is a command script that does routine upkeep tasks in a HylaFAX spooling directory hierarchy. This script is intended to be
invoked from cron(8) on behalf of the fax user (often the ``fax'' user is uucp) once a day, with the standard output sent by mail to the
HylaFAX administrator. For example, the following crontab might be set up for the fax user:
25 23 * * * sh /usr/sbin/faxcron | mail FaxMaster
The faxcron script does the following work:
o report statistics for facsimile transmitted since the last time faxcron was run.
o report statistics for facsimile transmitted in the past week.
o report statistics for facsimile received since the last time faxcron was run.
o report statistics for facsimile received in the past week.
o report any recent calls that failed suspiciously and return the associated trace log;
o purge data that is 30 days or older from the remote machine information directory;
o delete information that is 30 days or older from session trace log files;
o remove files from the tmp directory that are older than 1 day;
o remove files in the received facsimile queue that are 7 days or older;
o report sites that are currently having jobs rejected; and
o force all session log files to be owned by the fax user and kept with protection mode 644.
OPTIONS
-n Forces faxcron to run without updating any files.
-l lastrun
Forces the notion of the last time that faxcron was run to be lastrun. The value of lastrun is a date and time string of the
form ``MM/DD/YY HH:MM'' (the date(1) format string ``%D %H:%M'').
-info n Set the expiration time for data in the info database to be n days.
-log n Set the expiration time for session log data to be n days.
-rcv n Set the expiration time for files in the received facsimile queue to be n days.
-tmp n Set the expiration time for files in the tmp directory to be n days.
-mode m Set the file protection mode for session logs to m (a command line argument to chmod(1)).
NOTES
This script requires nawk(1) or gawk(1) and a date (1) program that supports the ``+format'' option.
If session logs are to be kept private this script must be modified to filter out sensitive information such as calling card numbers. (It
should also be run with ``-mode 0600'' so that session log files are not publicly readable.)
