Synology seems to further favor their “own” (re-labeled, Toshiba- and Seagate-produced) drives instead of the numerous other once which still appear in the official HCL like we knew it over the years, starting with the 25-Plus-models.

I chose QNAP and the biggest reason was that I can open that bad boy to add RAM and a NVME to install whatever OS I want. i’m currently running openmediavault with no QNAP software. It feels nice imo.
I’ve had two QNAP NAS fail on me, never again. The first failed shortly after the 3-year warranty expired and was MSRP $600. The second failed right before warranty expiration with MSRP $1200 thinking a better unit would be less prone to fail, but alas.
Thankfully I was able to RMA to get my data back (proprietary RAID), and while waiting on RMA to return, built a custom TrueNAS server I can service all parts on myself for around the same cost of a new NAS. Sold the RMA unit on eBay to recoup some cost as well. All I ever ran on those units was Plex and Samba\NFS file shares. Never again.
Do you have external access to the drives with the TrueNAS or are they internal?
