I have 2 80gig drives from my older systems....just used for system image backups. After I install my OS, update it, and install all my work stuff, I do a duplicate image backup of my OS....I keep one on each drive for redundancy.
I have a 500 gb drive that serves as my OS drive and programs.
I also have a 1tb internal drive for data only.
...and finally a 1tb external drive that is used for data backups.
Previous benchmarks were done with PC Wizard 2010 and 2012. I saw KC's new PC topic and ran the PC Wizard 2008 version and scored a global score of 197563. If I unplugged the 2 8 year old 80 gb drives that I use for basic storage of some old unimportant pics and files, I would probably score higher.
