5 Best Hard Drives for Plex in 2021

Plex is a service that allows users to aggregate their media files into one device called a Plex Server from where the files can be accessed from other devices.

If you have a library of movies, for example, you can designate a computer to act as the server, store your movies there, and with an app on your phone, you can stream your media files.

It allows file sharing at a more user-controlled level. To pull it off, you’ll need the best hard drives for Plex. These are more durable and can work for longer.

While you HDD make the most sense for Plex server due to their lower cost per GB, some people also prefer installing SSD. We look at both below.

How to Choose the Right Plex Hard Drive?

With media servers, the idea is to have your content available when needed.

This entails having the computer running as the server, operate continuously for long periods.

This can introduce a lot of stress to the system, especially spinning hard drives that are prone to mechanical failures that can lead to data loss.


When it comes to endurance, think long term operations. Whichever hard drive you’d like to use for Plex, it should be one that can run 24/7 with a low chance of failure.

A desktop hard drive will be good enough for a plex server; however, these drives were not built to run continuously for days on end.

NAS Drives

Media Server Grade Hard Disk for NAS as generally the best choice for Plex

Instead, there are options like NAS (Network-Attached Storage) drives that can run continuously for long durations.

These are typically designed to endure the long operations of a system that’s built for high availability and are a great choice for Plex.

Enterprise Drives

Data Center HDD
Some HDDs have a high TB/year work load rating particularly Data Center grade. They are highly reliable but expensive.

These are also a great choice. Many are built to handle large workloads and maximum up-time to support modern data centers.

The problem with these drives is that they tend to be very expensive and may not be a good pick if all you want to do is to store your movies.

Regardless, cost aside, these drives are great and have great endurance and good performance.

Surveillance Drives

Video surveillance systems use hard drives that operate 24/7. They can record data from multiple cameras simultaneously and even stream that data.

These drives can be great for a Plex server because of their high endurance. However, some users have pointed out that they have some performance issues like low speeds and frame drops when streaming.


Besides endurance, you will also want a hard drive that performs well. When your plex server needs to stream to multiple devices concurrently, a low-speed drive will show some issues.

SSDs are very fast and have high bandwidths to allow you to stream from multiple devices without issues.

Storage Capacity

You need to consider storage capacities especially when your media library is expected to grow. You may swap out smaller drives for larger ones when you’re running out of space, but good planning at first will help a lot.

Also, you need a drive that can implement auto-backups. This will come in handy in the event of a disk failure you forgot to manually do the backup.

The following video sums up the process very well.

Final Words

In short the best hard drives for Plex are those that are suitable for media servers. Hard drives that are built for NAS, that are reliable and have a high mean time between failures are highly recommended for plex servers.

Alternatively, any large capacity hard disk can do just fine. You don’t necessarily have to use an SSD. However, if there are multiple users using the same storage, then you will certainly benefit from an SSD.

You can also choose to go for cloud based external HDD that have specific support for Plex servers.
