ASK NC

I have been binge-watching your website for a few days and I truly appreciate your time and work in putting all this together.
Even though I have managed to get a general idea of NAS and Plex media servers, I am still unsure on which devices to consider.

Key info:
- This would be my first NAS
- Preference for Synology and 4 bay
- Able to play 4K downloaded content of 35 to 50GB files (most of times .mkv)
- Mainly to be played on TV and commuting to work on 2 devices (lower quality streaming) / never more than 2 devices streaming
- Able to backup my data and access it anywhere
- I have a Sony Bravia smart TV from 2017 (KD-55XD7005)
- Wi-fi is 1 Gbps download / 75 Mbps upload

Question:
I saw the Synology DS920+, DS720+, and DS423+. Based on the above which one do you think would be the best option for me? Or is there any other model you would recommend?


Thanks a LOT in advance for your opinion.

All of these NAS come with the same CPU and performance. The real question here is the price and necessity for 4 bays.
In terms of accessing your data from anywhere, all three models come with Synology's DiskStation Manager (DSM) operating system, which includes various remote access and cloud synchronization features. These features allow you to access your data from anywhere with an internet connection, as well as sync your data with cloud services like Dropbox, Google Drive, and Microsoft OneDrive.
