Best NAS for Plex Reviews and Buying Guide


A very well-liked media server software choice is Plex. Plex is one of the easiest-to-use media server tools, albeit it’s not the only one out there. The server functionality of Plex still takes center stage, despite the addition of free, authorized streaming media, podcasts, and live over-the-air television. As a result, you’ll need network-attached storage (NAS) device in addition to a great Plex client. View the top NAS for Plex alternatives, including servers and NAS boxes!

What is Plex?

Plex can be compared to a DIY version of Spotify or Netflix. With a media server, you provide the movies, TV shows, and music files as opposed to streaming services like Netflix, Hulu, and Vudu hosting the content. You can then view your movies, TV episodes, and songs on a variety of devices from nearly anywhere after Plex organizes your library with metadata and box art.

However, Plex adds a tonne of cord-cutting capabilities like the ability to use an OTA antenna for live TV and DVR capability, as well as web series and podcasts, as well as free, legal, ad-supported streaming of movies and television episodes. It’s one of the greatest applications for cord-cutting as a result. You need a Plex server, a Plex client, and a library of movies, television shows, and music albums to get started with Plex. These media can be obtained via DVD, Blu-ray, or CD rips.

What is a NAS and How Does it Work?

An Internet-connected file storage system is known as a network-attached storage device. In this approach, files on a NAS can be accessed both inside and outside of the local area network. It functions similarly to a server but is more self-contained. A NAS box, for instance, is typically a ready-made system with a CPU (central processing unit), RAM, and hard drive bays.

Network-attached storage units frequently include processors that cannot be upgraded by the user and little RAM. Memory can occasionally be upgraded. A DIY server might have a Linux distribution (distro) installed instead of the proprietary operating system (OS) that many NAS boxes from companies like QNAP and Synology ship with. The majority of NAS devices place a strong emphasis on simple setups.

Although servers often come in either more conventional desktop form factors or rack mount server footprints, they generally achieve the same task as a NAS. A server will often have more processing speed, memory, and upgrade potential. However, servers are frequently more expensive and less user-friendly.

Using Plex to build your own media collection and stream movies and TV shows from it can be a terrific idea. You won’t need to use any services like Netflix or Prime Video after setting up a Plex server. However, in order to set up a Plex server, you’ll need something like the best NAS for Plex listed below, which has been chosen based on these criteria:


Your NAS’s CPU manages all of the file access requests it receives, much like a computer would. Additionally, if this CPU isn’t quick enough, Plex may slow while streaming media from your NAS. Therefore, choosing speedier quad-core CPUs like the Intel Celeron J4125 over dual-core CPUs like the Marvell Armada 7020 is recommended.


The amount of RAM it offers is another thing to consider before purchasing a high-performance NAS for Plex. This is because a NAS with 4 GB DDR4 RAM will perform better than one with 4 GB DDR3 or 2 GB DDR3 RAM since more RAM ensures smooth playback of streaming content.

Drive Bays:

Checking the total number of drive bays your NAS offers is a wonderful idea if you want to build a Plex server with a lot of storage space because that will determine how many drives you can fit inside. The majority of NAS for Plex typically include 4 or 5 drive bays, which should be adequate for storage capacity and redundancy drives.

While you should definitely take these things in mind when purchasing a NAS for Plex, you can also discover a comprehensive “Buying Guide” that will help you choose the ideal option.

For instance, your server will need to convert a 4K video you have stored in a format that isn’t supported by your TV when it is streaming.

When compared to merely providing a file over the network, this consumes a lot of CPU. A 4K movie can be transcoded on the majority of Intel Celeron CPUs, but ARM processors are absolutely out of the question. The price and quality of the support for transcoding increase with NAS power.

What makes a good Plex server?

An i3 processor and 2GB of RAM are minimum requirements for a good Plex server. Plex suggests using an Intel Atom 1.2GHz processor for no transcoding, an Intel Core i3 3.0GHz processor for one 720p transcode, an Intel Core i5 3.0GHz processor for one 1080p transcode, or an Intel Core i7 3.2GHz processor for one 4K transcode.

Is the Plex media server good?

Yes! With its robust media server capabilities, cord-cutting tools, frequent updates, and excellent device support, the Plex media server is the finest media server software for the majority of users.

Do I need a graphics card for Plex?

No! Although a graphics card can aid in hardware-accelerated transcoding, a GPU is not required for Plex.

How much RAM do I need for a Plex server?

For a Plex server, you’ll need at least 2GB of RAM, while 4GB or more is preferred.
