Sd cards aren’t meant to be constantly written to, games are fine by themselves, but the windows OS is CONSTANTLY reading files, making changes, writing logs, deleting temp files, and writing over them, etc.

It won’t happen immediately, and it will depend on the grade SD card you get, but eventually your sd card is going to fail and you’re either going to lose data or your windows install will start chugging cause the SD can’t keep up with the writes anymore. Plus, the SSD will be closer to the bus and get faster r/w anyway.

I assume the people who go around saying its not a problem just got a higher end card or are lucky and haven’t had a problem yet.

Its essentially the same argument as “smoking will give you cancer”
