ASK NC

Hello,
I recently purchased a Asustor Drivestor 4 Pro AS3304T - 4 Bay. I'm not happy with it and I'm thinking of returning it. What would you recommend as a upgrade or replacement?

Requirements:
4 bays or more (so I can do RAID 5)
SSH access
expandable

Nice to have:
Media server, Jellyfin
remote access
HDMI output

After looking at your channel I'm thinking a QNAP or a higher end Asustor. I want to spend less then 1,000

Yes, AS3304T is a quite weak NAS.
If you need a multimedia NAS, you should look at Quad core Celeron-based models or better.
People love TVS-473A with PCI GPU card. But, you may not need that much performance unless you want to transcode 4k remotely in Plex.
Built-in Video apps can handle 4K even in Realtek and Celeron.
HDMI NAS only is made by Qnap and Asustor. Have a look at TS-464.

I hope this helps.
