Best Storage Size for Your Raspberry Pi (Expert tips)

Figuring out the best storage size for your Raspberry Pi can be a bit tricky. You can use SD cards or USB drives, but it’s hard to know which size is best. But don’t worry. I’ve tested a bunch of options and have some solid advice on what works best.

As a general rule, 32 GB of storage space would be enough. The Pi is not isn’t the most demanding computer. You can even go lower. After that, it highly depends on the storage needed for the applications and personal documents.

In this article, I’ll give you more details about this short answer, what my reasoning is and the options I recommend for your main storage.

If you need help getting started on Raspberry Pi, I have an entire course to guide you through your first steps. I’ll help you use the perfect hardware, plug everything in and install your first system. You’ll also do your first projects with me, just to make sure you are ready for the next level.

How much storage do you need for Raspberry Pi?

If you want to run an operating system on your Raspberry Pi computer, you would actually need a micro-SD as the storage for your computer. Yes, you won’t need anything large such as an entire hard drive. A micro-SD will be enough for your Raspberry Pi computer.

How much space for your Raspberry Pi?

A Raspberry Pi with just the base operating system doesn’t take up much space. Something as small as 8GB would be enough for a Raspberry Pi computer. However, in most cases, 8GB could be a fast limit for adding new applications and features.

In that regard, you can use a 16 GB micro-SD card, which is usually the most common option for a lot of casual Raspberry Pi users out there, as they believe that 16 GB of storage space is enough for most of their computing needs. It might even be more than enough if you are only using your Raspberry Pi casually.

I recommend starting with a 32GB option to make sure you have enough storage for future projects. Storage is cheap, but your time isn’t. You don’t want to spend weeks reinstalling your system just because you need some extra space.

If you have a 32 GB micro-SD card for your Raspberry Pi, it would certainly be more than enough as 32 GB (or less) is the recommended storage space for your Raspberry Pi computer.

By the way, following the results of a poll I made on my YouTube channel, the 32 GB option seems the most commonly used among my subscribers. There are 44% of the Raspberry Pi users who have a 32 GB SD card, while 18% are using a 64 GB and 16% with 16 GB or less.

Still, you do have the option to go bigger by using a 64 GB card, which should be more than enough storage for your Raspberry Pi computer, although you can still go for bigger (the maximum is currently at 1 TB, example here on Amazon). Bigger will always be better, but there is a catch.

Raspberry Pi’s bootloader will only support reading from file systems that are formatted as FAT16 and FAT32. In case you did not know, micro-SD cards that are 64 GB or higher come with the exFAT file system format. That means that you cannot use your 64 GB right out of the box, and you will have to reformat it to FAT32 in order to use it for your Raspberry Pi computer.
Typically, Etcher and Raspberry Pi imager will automatically handle this, but it can cause weird issues for specific distributions.

How much storage do you need for each Linux distribution?

As a general rule, a 16 GB micro-SD card will be enough to install any of the most popular distribution for Raspberry Pi. This is the minimum required to install it, it doesn’t count the packages and files you’ll add later.

Raspberry Pi System	Image Size	Minimum SD Card
Ubuntu Desktop	8.75 GB	16 GB
Raspberry Pi OS Full	8.61 GB	16 GB
Manjaro 64 bits (XFCE)	5.34 GB	8 GB
Raspberry Pi OS Desktop	3.97 GB	8 GB
Batocera	3.50 GB	8 GB
Recalbox	3.23 GB	4 GB
Retropie	3.11 GB	4 GB
Raspberry Pi OS Lite	1.87 GB	4 GB
DietPi	1.07 GB	2 GB
LibreElec	0.58 GB	1 GB
Lakka	0.57 GB	1 GB

For example, Lakka requires less than 1 GB to be installed on your SD card. But once installed, you will transfer games ROM that can quickly increase the required storage space. Most PlayStation games are over 512 MB each for example.

Same thing on Raspberry Pi OS. A 16 GB SD card will be enough to install any version. If you use it as a desktop computer, you’ll quickly add downloads, documents and new applications which might double the space you need rapidly.
That’s why it’s probably a good idea to go for a 32 GB SD card minimum (and that’s what most users seems to do in our poll).

How to add storage to Raspberry Pi

As mentioned, bigger will always be better when it comes to storage space. This applies to your Raspberry Pi computer. However, there might be a tiny issue when it comes to using bigger micro-SD cards such as 64 GB or higher.

Most of the time, Raspberry Pi Imager and Etcher will create a partition to the size required by the image file. Then, most operating systems (like Raspberry Pi OS), will expand the partition size to the maximum available on first boot. You have nothing to do in this case. But don’t forget to check that on more exotic distributions. The first step after installing some system is to expand the partition yourself.

Alternatively, you can also expand your storage space in your Raspberry Pi computer by making use of a USB storage device. This is the best way for you to expand the storage space of your Raspberry Pi computer because it allows you to ensure that you will never run out of storage space because you can just swap out your USB storage device for another one. And if you are using a recent Raspberry model (3 and above), you can even install the OS on the USB storage device.

You can use plenty of different USB storage devices for your Raspberry Pi such as a compact flash drive, an external hard drive, or even an SSD, which is a good option for you because of its speed and power (here is my favorite SSD by the way).

Raspberry Pi storage options 

Here are some of the storage options you have for your Raspberry Pi computer:

SanDisk Ultra 32 GB

SanDisk Ultra 32 GB is the best for general computing purposes because it pretty much covers everything you need as far as storage size is concerned. However, this isn’t the best option if you are going after speed because it isn’t the fastest micro-SD card on the market.

Still, it also isn’t the slowest as well, and that is why it sits right at the middle as the best for general computing especially if you really don’t care enough about speed, but you need enough storage space from your micro-SD card. You can check SanDisk Ultra 32 GB here.

SanDisk Extreme Pro 32 GB

The SanDisk Extreme Pro 32 GB, which you can find here, has a similar storage size to the Ultra 32 GB. But the difference here is that this micro-SD card trumps its Ultra counterpart in terms of its speed and performance.

This makes it the better choice for those who need storage and power such as when they are playing games or when they’re using their Raspberry Pi computers for tasks and applications that require more speed and power from the storage device.

Samsung EVO Select 64 GB

While 32 GB micro-SD cards are usually already more than enough for most people, there will still be some Raspberry Pi users who may not be content with 32 GB storage – especially if they are using their computers for gaming. That is where the Samsung EVO Select 64 GB comes in as it has double the storage space of most of our other options on this list. Moreover, it also comes with power that is comparable to the SanDisk Extreme Pro especially when it comes to its writing speeds.

Just don’t expect it to be cheap because it does come with more storage space. Check it out here if you are interested.

Kingston Canvas Select 16 GB

If you are really only using your Raspberry Pi computer for basic computing functions such as browsing and for creating certain documents, you wouldn’t need anything that is more powerful than the Kingston Canvas Select 16 GB. This micro-SD card is also the cheapest option that we have for you as it really doesn’t cost a lot, but it can get the job done as far as basic functions are concerned. It comes with the right speed and the right storage space for most of the casual Raspberry Pi users out there.
