Flash drives and Micro SD cards / regular SD cards suffer from both the data saved on them being unreliable and also often very slow read and write speeds. So you will be significantly slowing down how fast bazzite can work, as well as risking your data by running it off of either a flash drive or MicroSD card.
ok i understand. so i should put it on the D drive (SSD). i was worried about data loss, but Kyle assured me that won't happen so long as each OS is on a different drive
As a general reminder for any operating system, you should be backing up important files somewhere besides your own computer in case of a fire or a something going catastrophically wrong.
