It really depends on what types of games you're looking to play and how big the file sizes are. For example, if you're just playing basic PC games like League of Legends, 2TB SSD should be more than enough space. However, if you're looking to play more graphically demanding games like Witcher 3 or Fallout 4, you might need a bit more storage space since those file sizes are much larger. Overall, it really varies based on your specific needs but 2TB SSD should suffice for most people's gaming needs.
