Why I stopped using RAID on my Plex media server


RAID is typically the go-to method for redundancy in servers, and it definitely has stood the test of time. What if I told you I intentionally stopped using RAID on my Plex server? Here’s why.

RAID requires all drives to be the same size

My first home-built NAS ran on TrueNAS, which utilizes a traditional RAID structure for its drives. While TrueNAS handles all the RAID software-side (which I’ll get to why that can be important in a moment), I still was almost immediately turned off from using RAID.

One of the biggest drawbacks to RAID, in my opinion, is that it requires all drives to be the same size. I had a wide range of storage drive sizes that I wanted to use for my NAS, including 3TB, 4TB, 6TB, and 8TB drives.

Which Type of RAID Should You Use For Your Servers?

RAID, or “Redundant Array of Inexpensive Disks,” is the process of combining multiple hard drives or SSDs in parallel as one logical volume, making the array more resistant against drive failures.

With traditional RAID, all of those drives would have been limited to 3TB of storage. This means that I’d only use 50% of the available space on the 6TB drives, and around 35% of the 8TB drives. The rest would sit unused.

This felt like a waste to me. I had the drive space, why couldn’t I use it? I understand how RAID works, and why it works that way, but I wasn’t happy with it. There had to be a better solution.

If your RAID controller fails (or even your OS), the data is gone

While TrueNAS (and other software-based RAID systems) can typically be “portable” in that you can move the OS (Operating System) to a new system and your data goes with it, that still makes you rely on that OS not to fail. The operating system has the information pertaining to what data goes on what drive, and that’s the only way to access the data.

If you use a hardware-based RAID controller, and the controller dies, there’s a chance your data is gone too. The drives could be completely fine, but if the RAID controller goes corrupt, there’s a chance you lose your data.

With the way that RAID works, if you don’t have the “key” that tells the system how to decode the drives, none of the information is accessible.

This was something I didn’t want to leave to chance. Hardware fails, operating systems get corrupted, and I wasn’t a fan of leaving my data in the hands of those things. Sure, lots of people do and failures are rare, but why put it to chance?

Just like the limitation of having all the drives the same size (or limited to the smallest drive), I knew there had to be a better solution to my storage woes—and I was right.

Unraid’s parity system solves all of these problems

Where RAID fails me, Unraid succeeds. Yes, Unraid is a paid operating system with its own limitations, but it does everything I need and more.

Instead of relying on RAID, Unraid uses a parity system to keep your data redundant. Essentially, the way Unraid’s parity works is that it uses a calculation of the parity drive plus all of your other drives to know what the parity drive should be set to. Either a 0 or 1.

This happens for every bit on the drive, and it means you can use drives of any size in the server without issue. The only limitation to drive size is the size of your parity drive. It has to be the biggest (or equal to the biggest) drive in your system.

My current Unraid server uses a 12TB drive for parity, and then I have 4TB, 6TB, and 8TB drives under it that all combine to give me the storage pool I have access to. When I want to swap things around, I just spin the array down, pull a drive, and replace it. It then rebuilds the parity, and I’m good to go.

Why I Chose Unraid Over TrueNAS Scale in 2025

Unraid is just better.

Another way this is nice is when you have a drive failure. I know, drive failure and nice in the same sentence? Sometimes.

I recently had both a 6TB and 4TB drive fail on my Unraid server. Since I had plenty of storage space left on the other drives, I actually was able to move data from the failed drives to the good drives and then just remove the failed drive from the array.

How is that possible? Well, unlike RAID, which distributes pieces of files across all drives, Unraid stores whole files on each drive and gives you access to them directly. In fact, you can pull a drive from an Unraid server and plug it into any Linux machine to access the data.

This means that I’m not worried about a RAID card or OS failure putting my data at risk. I might lose my array configuration and have to rebuild that to get the server up and going, but I can access my individual drives and the files they contain from nearly any computer.

All of this combined to give me more flexibility and capabilities than I’d typically get from a traditional RAID array. Sure, Unraid’s read and write performance are less than that of ZFS, but the storage capabilities are much greater.


You should try Unraid, too

This is just one of the reasons I chose Unraid over TrueNAS for my home server. There are several other factors that went into the decision, and price isn’t even on the list.

I think Unraid is worth every penny when it comes to the price the team charges. It’s a fantastic piece of software, extremely user-friendly, and runs on almost any hardware—including old enterprise-grade servers from eBay.

Google Maps has a long list of hidden (and sometimes, just underrated) features that help you navigate seamlessly. But I was not a big fan of using Google Maps for walking: that is, until I started using the right set of features that helped me navigate better.

Add layers to your map

See more information on the screen

Layers are an incredibly useful yet underrated feature that can be utilized for all modes of transport. These help add more details to your map beyond the default view, so you can plan your journey better.

To use layers, open your Google Maps app (Android, iPhone). Tap the layer icon on the upper right side (under your profile picture and nearby attractions options). You can switch your map type from default to satellite or terrain, and overlay your map with details, such as traffic, transit, biking, street view (perfect for walking), and 3D (Android)/raised buildings (iPhone) (for buildings). To turn off map details, go back to Layers and tap again on the details you want to disable.

In particular, adding a street view and 3D/raised buildings layer can help you gauge the terrain and get more information about the landscape, so you can avoid tricky paths and discover shortcuts.

Set up Live View

Just hold up your phone

A feature that can help you set out on walks with good navigation is Google Maps’ Live View. This lets you use augmented reality (AR) technology to see real-time navigation: beyond the directions you see on your map, you are able to see directions in your live view through your camera, overlaying instructions with your real view. This feature is very useful for travel and new areas, since it gives you navigational insights for walking that go beyond a 2D map.

To use Live View, search for a location on Google Maps, then tap “Directions.” Once the route appears, tap “Walk,” then tap “Live View” in the navigation options. You will be prompted to point your camera at things like buildings, stores, and signs around you, so Google Maps can analyze your surroundings and give you accurate directions.

Download maps offline

Google Maps without an internet connection

Whether you’re on a hiking trip in a low-connectivity area or want offline maps for your favorite walking destinations, having specific map routes downloaded can be a great help. Google Maps lets you download maps to your device while you’re connected to Wi-Fi or mobile data, and use them when your device is offline.

For Android, open Google Maps and search for a specific place or location. In the placesheet, swipe right, then tap More > Download offline map > Download. For iPhone, search for a location on Google Maps, then, at the bottom of your screen, tap the name or address of the place. Tap More > Download offline map > Download.

After you download an area, use Google Maps as you normally would. If you go offline, your offline maps will guide you to your destination as long as the entire route is within the offline map.

Enable Detailed Voice Guidance

Get better instructions

Voice guidance is a basic yet powerful navigation tool that can come in handy during walks in unfamiliar locations and can be used to ensure your journey is on the right path. To ensure guidance audio is enabled, go to your Google Maps profile (upper right corner), then tap Settings > Navigation > Sound and Voice. Here, tap “Unmute” on “Guidance Audio.”

Apart from this, you can also use Google Assistant to help you along your journey, asking questions about your destination, nearby sights, detours, additional stops, etc. To use this feature on iPhone, map a walking route to a destination, then tap the mic icon in the upper-right corner. For Android, you can also say “Hey Google” after mapping your destination to activate the assistant.

Voice guidance is handy for both new and old places, like when you’re running errands and need to navigate hands-free.

Add multiple stops

Keep your trip going

If you walk regularly to run errands, Google Maps has a simple yet effective feature that can help you plan your route in a better way. With Maps’ multiple stop feature, you can add several stops between your current and final destination to minimize any wasted time and unnecessary detours.

To add multiple stops on Google Maps, search for a destination, then tap “Directions.” Select the walking option, then click the three dots on top (next to “Your Location”), and tap “Edit Stops.” You can now add a stop by searching for it and tapping “Add Stop,” and swap the stops at your convenience. Repeat this process by tapping “Add Stops” until your route is complete, then tap “Start” to begin your journey.

You can add up to ten stops in a single route on both mobile and desktop, and use the journey for multiple modes (walking, driving, and cycling) except public transport and flights. I find this Google Maps feature to be an essential tool for travel to walkable cities, especially when I’m planning a route I am unfamiliar with.


More to discover

A new feature to keep an eye out for, especially if you use Google Maps for walking and cycling, is Google’s Gemini boost, which will allow you to navigate hands-free and get real-time information about your journey. This feature has been rolling out for both Android and iOS users.
