I had built a PC just for Zwift about 2 years ago - went with a 2.5 inch HDD…and boy was it a dog to load. Zwift would often take like 10 minutes to load. I’ve missed a few rides due to the lag. I finally got around to installing an SSD and want to share that loading is super quick now - and i can be ready to ride within 5 minutes when before the SSD was installed i needed at least half an hour for everything to be loaded properly.
So if you’re still using HDD - go get a SSD - it’s a game changer for me.
