ASK NC

Hi guys, need help choice good model NAS for me,
First maybe what I need, I need NAS for backup PC Hd, data from 3 phones (mostly pictures,big files video 4 or 8k-sometimes 5gb file) and want use 3-4 IP camera (mostly on onvif protocol), I can connect nas and PC by 1x SFP+ port and also 1x10gb Ethernet in my router, or ling 2x1gb lans,
Thinking between
QNAP TS-431KX ( because SFP port)
Or
QNAP TS-251D
Or
QNAP TS-431KX
Or maybe something different under 400£?
Thanks advance for help

If I need to choose between these NAS, I would pick QNAP TS-251D or 53D. These are multimedia-friendly options. Qnap 31K series are made for backups only.


I hope this helps.
