If you're doing data intensive operations (like a big update which looks
like what you're doing) it will write many megabytes to the harddrive...
my laptop HDD (5400 rpm) does about 15 MB/s throughput while a standard
desktop 7200rpm drive does 55-60 MB/s throughput. Plus, seek times on a
laptop drive are horrendous.
