New Setup, Seagate Skyhawk HDD

I am diving into the world of TrueNas for the first time. I have an old Dell Optiplex and loaded it with 3 drives.

From my quick research, I gathered that the boot drive does not need to be anything special, so I threw on there a generic chinese 512 SSD I took out of a refurbished device I bought off Amazon. This will be running TrueNas, backing up the configuration files to an external USB stick.

I then added two 2-TB Seagate Skyhawk HDD (ST4000VX013-2XG104) set up as mirror. Did some testing and all is looking good.

As I was researching info on some apps to add on to the TN, I ran into a post abut ZFS not playing nice with SMR (Shingled Magnetic Recording) drives such as the Seagate Skyhawk HDD. Went down that rabbit hole and now I am shook!.

I will be using this setup to run Immich and file storage, basically to start getting off the GDrive and GPhotos of the world. I dont think I have 1TB of data all together, and thats between my wifes and my data. Maybe down the line I may run Jellyfin or Plex as the kids get older and start getting into movies and shows.

So before I start throwing data into these drives, will this be an issue, even in MIRROR mode?
