I keep it simple. Install OS on SSD as C:\ as well as Office and most ordinary apps. 2 or 3 x 2TB HDs as E:\, F:\, G:\ etc with optical as D:\ or E:\ if you have two. Then games (Steam dir is 1TB and growing! ) goes on one of the HDD's. Backups (of the SSD) on another and crap, scratch, temp, dump, "working" drive for the other. I also have 3 x NAS devices - 1 x QNAP TS-659 Pro II (6x3TB's in RAID 5) and 2 x Thecus N5200Pro and N5200Pro XXX - (2 x 5x2TB'sin RAID 5). The Thecus are for work and the QNAP is for play. The new Thecus backs up to the old Thecus. In the old days I partitioned drives. Now I don't bother, I just use the drive as the natural partition. Why bother? Drives are so cheap what's the point. Even on a laptop I used to bother with partitioning but now I just install the whole drive as C:\ and keep a folder for my working area. NASs, IMAP, cheap HDDs (and cheap light external drives) have removed the need for partitioning for me. My 2 cents.
