A 5400 RPM is fast enough to service the IO required to load the textures used in Wow, interraction with the pagefile that is most likely causing this. If your experiencing this, max out your Ram before buying a 10k hard disk.
On a busy server while flying into Shatt, I can guarantee a 5400rpm drive isn't enough to handle loading all the data needed for 5-boxing WoW. While using separate installs, before I symlinked to the /Data directory on my Raptors, I would occasionally have one of my instances of WoW crash due to a "Failed to read data" error from my 7200rpm drive. There were too many small I/O requests to keep up with the game, and it would crash since some I/O requests weren't being finished within a reasonable amount of time. This error never occurred after I symlinked the /Data directory to my RAID0 Raptors, but I'd still lag like crazy while flying into Shatt, and many players/objects/textures wouldn't show up for up to 20-30 seconds after landing. *All* of these problems went away after symlinking to a /Data directory on my SSD.

These were the primary links that convinced me to try out an OCZ Core SSD for WoW:
