Then I got the idea to buy a brand new high capacity, high speed thumbdrive (Patriot Supersonic Rage 2 256GB) as I thought it would be even better, but that's where I encountered the problem. Installation and persistence went fine, but as soon as I booted into the encrypted persistence environment and started running, I noticed everything was EXTREMELY slow on the new drive. I tried doing an apt update/apt upgrade but it literally took hours. I checked "top" and didn't see any offending processes. It was so laggy that I couldn't even log back in once the system went to the lock screen.
Just for grins, I went back to my old thumbdrive (the 2017 64GB Sandisk) and everything worked great, as if I were on bare metal.
Evidently it's happy with some USB drives but not others and the spec speeds don't seem to be the underlying issue...
An upgrade ussually takes 45min to 1 hour sometimes longer. Depends on your connection ect.
easy to start; hard to finish
