"iostat" gives more detailed disk statistics, based on /proc/stat: per
physical device, and with a kernel patch, per logical device. Thanks to
Eric Wolf for pointing this out.
"sar" shows similar statistics (and many other system statistics) and
has log record/view facilities. The Linux port is rather recent.
The "sysstat" package (RedHat7, Suse 6.4) contains both.
