Guide to Choosing the Right NAS for 4K Streaming:

4K is a term that’s used to denote the resolution of a digital screen. It is used as a measure of the details that the screen is capable of showing.

A typical 4K screen has in the UHD (Ultra HD) format has 3840 pixels along the width of the display while the height has 2160 Pixels. It’s called 4K because of how close the number of pixels on the horizontal is to 4000.

Typically, the high resolution gives better picture quality. This means the content you consume appears richer and sharper when viewed in 4K as opposed to other resolutions.

4K Streaming

With a media server, content gets streamed from one central location, usually over a network, to connected devices. This can happen over the local network or the internet depending on your NAS and your internet capabilities.

Streaming in 4K can be a bit demanding because the file sizes are large. These can be heavy on the processor of the NAS, handling the decoding and encoding of the files to different video formats as well as scheduling its transfer over the network.

Even the networking aspect can be a bit challenging because while you may easily get away with streaming in 4K from a NAS to one or two devices, having more devices will increase the load on the system, and if it’s not robust enough, you will experience some lags.

Streaming 4K with NAS

High processing speeds and decent amounts of RAM will enable multiple simultaneous 4K streaming from a NAS.

Besides having good specs, you will also benefit if you have a NAS that supports 4K video transcoding.

With transcoding, a video is converted from its original format to one that is playable via your media devices.

This can make playing files more efficient as you get playable media straight from the NAS instead of decoding and encoding it on your device which for large files can cause lags.
