It did 4 passes by default. It took almost 3 hours to run on 16 GB of RAM.
It’s possible there is an issue with the WiFi. I had lots of WiFi issues on this laptop when I used Windows (micro freezing when using typing into an SSH shell, and pings would drop at the same time), but since switching to Linux, those went away. I’ll definitely keep that in mind. I’ll try using wired network if the issues come back after swapping SSDs.
