Assuming that (1) your computer is a single user desktop/laptop and (2) you want a simple solution -- and not too many things to learn upfront!,
I would forget about all these partitions for /usr, /home, /opt... I would install all the OS filesystem in a single partition. As you are running Mint, I guess you have a beefy-enough configuration (enough RAM) so I would go without swap (or a swapfile in the OS partition, just in case).
I would use 4 primary partitions:
- sda1: 50GB - boot manager + main "workhorse" OS (Slackware 14.0)
- sda2: 50GB - experimental OS, eg. Arch
- sda3: 50GB - experimental OS, eg. Slackware current
- sda4: 850GB (rest of disk) - data, eg. your personal stuff, music, etc.
50GB is more than enough for running a modern linux (you may want to adjust according to your needs)
the large data partition can be mounted in whichever OS you happen to use. If you have confidential or private stuff on this PC, you may want to set it as an encrypted partition (dm-crypt/LUKS).
