Between discussions of RAID0, SSDs in RAID, hard drive access, etc, I think you are definitely in the minority on thinking harddrive access time has little to do with multiboxing. After having enough RAM, many would say an SSD is the best upgrade your system can make.
How often do you boot your machine in comparison to how often do you see a load screen for WoW? I use my computer to primarily play video games so that question is very easy for me - I'd much rather wait an extra 15 seconds for my computer to boot using the 7200 drive and have my WoW loading screen be near instant. WoW is somewhat intensive on accessing the harddrive, but nothing big. A single player wouldn't really need an SSD. However, a 5 boxer will see a huge performance increase from moving from a single 7200 drive to even a slow SSD.
