Looking for someone to run a sanity check on my setup
I got into homelabbing a few months ago and have an aging laptop that is running as my home server for now but running out of disk space. Rather than buy a DAS, I’m planning on replacing the whole setup with a UGreen 4800 pro. There is a soldered 128gb nvme for a boot drive and 2 nvme slots and 4 SATA slots.
The built-in 128gb boot drive will be wiped for bare metal Debian that I am comfortable with. I have 2 1TB nVMEs that I will install. These will be for my docker apps, particularly immich (high I/O) and a file share, and also a write cache for downloads from torrents, which will flush to hdd overnight and delete torrents after ratio hits 1.5-2. This is to avoid spinning up the disks with lots of random I/O from the torrents. Should the nvme be BTRFS? Mirrored? Not sure. I will have an external hdd always attached that will automatically pull the photos/share drive nightly and every couple months or so, I will take this drive to my moms place and transfer all to another external hdd that is essentially in cold storage.
The 4 hard drives, I will buy sequentially as needed, probably a single high capacity drive to start. They will be JBOD with ext4 and mergefs, almost exclusively for movies/shows.
Anything seem obviously wrong or dumb in this setup? Wanted someone more experienced to give me their thoughts before I pull the trigger
