Qnap TBS-453DX was discontinued soon after its release. It was a good spec NAS, but people found it too complicated to install M.2 SSD. It also was too expensive to get a decent capacity. So they released an alternative: HS-453DX. And also at the end of the year, new TS-453D might come out. Recommended drives will be WD Red or Seagate Ironwolf. And all of these can be expanded to 16GB RAM if you do need this much RAM.I hope this helps.
