In a sudden turn of events, Blizzard has announced that World of Warcraft Shadowlands now needs a 100GB SSD for a minimum requirement, but does this mean you can not run the game with a regular spinning hard drive? A few Shadowlands beta testers have reported that running the game in an HDD has not affected their performance or gameplay in any significant way.
However, it is most likely a good idea to run this game on an SSD anyhow (here is our list of Greatest SSDs). It is also possible to possibly experience"hitching" in which the HDD is not fast enough to flow assets in real time.
