The Ultimate Buying Guide: Network Attached Storage (NAS) for Your Plex Media Server
Setting up a dedicated Network Attached Storage (NAS) device for your Plex media server is a fantastic way to keep all your movies, music, and photos safe and accessible. A NAS acts like a personal cloud, letting you stream content to any device in your home—or even outside it. Choosing the right one requires knowing what really matters. This guide breaks down the essentials.
Key Features to Look For
When shopping for a NAS to run Plex smoothly, focus on these core features:
- CPU Power: Plex often needs to “transcode” media. This means changing a video file format on the fly so your TV or phone can play it. A weak CPU will cause stuttering. Look for Intel CPUs, especially those with Quick Sync Video support (like newer Celeron or Pentium chips). These handle transcoding much better than basic, low-power chips.
- RAM (Memory): More RAM helps the NAS run multiple tasks at once, including Plex, downloading, and backups. 4GB is a good starting point for basic use, but 8GB or more offers smoother performance if you have many users.
- Drive Bays: This refers to how many hard drives you can install. A 2-bay unit holds two drives (good for basic backup). A 4-bay unit offers more space and better redundancy (safety).
- Networking Speed: Ensure the NAS has at least a Gigabit Ethernet port (1GbE). This allows fast transfer speeds to and from the device.
Important Materials and Components
The physical build quality impacts how long your NAS lasts and how quiet it runs.
The Enclosure and Cooling
Most NAS units use sturdy plastic or aluminum casings. Aluminum helps dissipate heat better, keeping internal components cooler. Good cooling fans are crucial. Loud fans ruin the experience, especially if the NAS sits in your living room. Check reviews for noise levels.
Hard Drives (The Storage)
The NAS box usually does not come with drives. You must buy them separately. Use drives specifically made for NAS use (like Seagate IronWolf or WD Red). These drives are built to run 24/7 and handle the vibrations of multiple drives spinning together.
Factors That Improve or Reduce Quality
The quality of your Plex streaming experience depends heavily on two things: hardware and storage configuration.
Improving Quality: Redundancy and Speed
The best way to improve reliability is through RAID (Redundant Array of Independent Disks). RAID configurations spread your data across multiple drives. If one drive fails, your data stays safe on the others. A 4-bay NAS running RAID 5 is a popular, safe choice. Faster CPU models dramatically improve transcoding quality, preventing buffering during playback.
Reducing Quality: Underpowering and Under-Speccing
If you choose a NAS with a very slow CPU and try to stream a brand-new 4K movie to an older phone (which forces transcoding), the stream will likely freeze or drop resolution. Also, using standard desktop hard drives in a NAS can lead to premature failure because they are not designed for constant operation.
User Experience and Use Cases
A well-chosen NAS transforms how you use your media.
Simple Streaming (Direct Play)
If your main goal is streaming high-quality 4K video directly to modern smart TVs that support the file format, you need less CPU power but more drive space. The NAS simply sends the file; it doesn’t need to change it.
Remote Access and Transcoding
If you want to watch your library while traveling, the NAS must transcode the high-bitrate files down to a streamable size for your mobile connection. This demands a powerful CPU. A good NAS lets the whole family stream different shows at the same time without slowdowns.
10 Frequently Asked Questions (FAQ) About NAS for Plex
Q: Do I need a dedicated computer to run Plex if I use a NAS?
A: Not usually. Most modern NAS devices can install the Plex Media Server software directly onto the unit, making the NAS itself the server.
Q: Can I use old external hard drives in my new NAS?
A: You can, but it is not recommended. NAS drives are designed for continuous, 24/7 operation, which standard external drives are not.
Q: What is transcoding, and why does my NAS CPU matter?
A: Transcoding changes a video file format in real time so your playback device can understand it. A strong CPU handles this heavy lifting without stuttering.
Q: How many hard drives do I need for good data safety?
A: At least two drives are needed for basic safety (RAID 1). For better space and safety, three or four drives in a RAID 5 setup are common.
Q: Is a 1GbE network connection fast enough for 4K streaming?
A: Yes, 1GbE is fast enough for multiple high-bitrate 4K streams, provided the NAS CPU can handle any necessary transcoding.
Q: Should I buy an empty NAS enclosure or one that comes pre-filled with drives?
A: Buying an empty enclosure gives you control over drive brand, size, and quality, which is usually the better long-term choice.
Q: Will a NAS use a lot of electricity?
A: Modern NAS units are very energy efficient. They use very little power when idling, though they use more when all the hard drives are spinning hard.
Q: What is the difference between Plex client and Plex server?
A: The Plex server runs on the NAS and manages the files. The Plex client is the app on your TV or phone that plays the media.
Q: Do I need to worry about running out of space quickly?
A: If you plan to store many high-quality Blu-ray rips, look for a 4-bay or larger NAS. You can always add bigger drives later, but plan for future growth.
Q: Can I use my NAS for things other than Plex?
A: Absolutely. A NAS is great for centralizing computer backups, running security camera storage, and sharing files across your home network.
