"Long-term sysadmins probably have vast depth of brutally-acquired knowledge about storage devices. Study one drive’s geometry so you can calculate the optimal cylinder grouping for each partition one time and that knowledge scorches itself into your brain. You develop a wholly natural desire to treasure and share that kind of trauma—uh, wisdom. Both authors are right there with you, but none of that matters in the age of ZFS so we’ve chosen to ignore geometry and MBRs and floppy drives and discuss only modern hardware."
