Your Raspberry Pi 4 doesn’t have any internal storage of its own so all of the software, including the operating system, runs off the SD card you supply. That means it’s essential to find the right card; one that’s fast enough, robust enough, has enough storage, and won’t break the bank. You can use any SD card, but here’s a list that will help you get the most out of your Pi.
Samsung’s 32GB EVO+ card ticks all the right boxes when it comes to using it in your Raspberry Pi 4. It’s fast enough, hits the maximum native format size, and it’s nice and inexpensive. If you’re not sure which card to get, pick this one.
If you need more space, the 64GB version of SanDisk’s Extreme Plus card is a great option as long as you correctly format it using the FAT32 file system. If you need the extra space, it’s worth it.
This 32GB card from Lexar isn’t going to win and speed tests when used in the Raspberry Pi 4. But it’s super cheap and perfect for someone who wants to save a little cash or likes to swap things up by using different software on different cards.
Kingston’s High Endurance card may not be the fastest out of the bunch, but you’ll make up for with durability and reliability. Read speeds come in at 95MB/s and write speeds hover around 45MB/s. Kingston also promises the card can withstand water, shocks, and just about anything else that could interrupt performance.
This 32GB card from SanDisk costs a couple of dollars more than some others, but it’s the fastest and best performing card in the Raspberry Pi 4 according to independent tests. If you need the slightly quicker read times, it’s money well spent.
Some of the performance gains will be lost when formatting as FAT32, but if you need the fastest 64GB card, this is it. Since we think 64GB is the maximum size you should use in the Raspberry Pi, think of this one as the gold standard.
A1 class cards don’t make a difference when used in the Raspberry Pi 4, but they also don’t make read and write speeds any worse. Buy this one because NOOBS OS — the Raspberry Pi Foundation’s operating system(s) of choice — is preloaded.
The SanDisk Extreme Pro was made with stability and ruggedness in mind, as it’s shockproof, waterproof, and even temperature proof. The card provides read speeds up to 100MB/s while also including a SD card adapter if you need to transfer files between your computer and the Raspberry Pi 4.
