ASK NC

I run Plex from a desktop to multiple TVs at home thru wifi, thru Roku Plex app. Occasionally another remote user accesses my Plex content.

Been looking to offload the workload from my desktop CPU. Thought NAS might accomplish this. I have approx 1TB of media, but with more capacity could quickly get up to 2TB, possibly 4TB in a year.

Almost all my content is 1080 or less. Most files are 2GB or less.

The NAS would be strictly a media server and file backup device.

Looking at the Terramaster F2-423 as a good value option.

But is a NAS necessary at all? Might I be better served with running ethernet cable thru the attic and upgrading internet service to 100MBps?

Yes, you could use any NAS for replacing your Plex server. Local streaming do not require transcoding.
You could also store your movies somewhere in the cloud if you wish.
Here is the internet speed you need for 1080p movie streaming from cloud:

Given that the movie is 90 minutes long and 1.5 GB in size, we can proceed with the calculation.

First, we need to convert the movie duration from minutes to seconds:

90 minutes = 90 * 60 = 5400 seconds

Next, we can calculate the data transfer rate:

Data Transfer Rate = File Size / Duration

Data Transfer Rate = 1.5 GB / 5400 seconds

To convert GB to MB, we need to multiply by 1024:

Data Transfer Rate = 1.5 GB * 1024 MB/GB / 5400 seconds

Data Transfer Rate ≈ 0.28 MB/s (rounded to two decimal places)

Therefore, the data transfer rate for a 90-minute movie that is 1.5 GB in size is approximately 0.28 MB/s.
