If I was to copy my World of Warcraft install to a USB thumb drive, would it improve or degrade performance? Or, as an in-game friend suggested, quickly destroy the thumb drive with all of the constant reading/writing?
I got the wild idea (haven’t actually tried it yet) to use a thumb drive as sort of a pseudo-SSD, mostly because I’m playing the game on a horribly outdated computer and load times are insane. My friend with the SSD can log in and out three or four times while I’m sitting there waiting to finish loading into Dalaran in the Broken Isles.
It is likely pointless. I doubt your HDD read/write speeds are your loading bottleneck.
That said, it’s easy enough to test. USB drives degrade with repeated rewriting, but not with repeated reading, so the ideal would be to have your main files stored on the fast disk but the game’s cached files written to your HDD.
