It bears repeating that when it comes to SD Cards there are three things to look at. Physical size, format, and speed. And of course, this applies when it comes to buying a microSD card for the Raspberry Pi 2 or 3. So let’s take a look at each before we give you our top picks of the best memory cards for Raspberry Pi.
Raspberry Pi micro SD card requirements:
There are different SD card sizes with a Standard SD card being the largest. The original Raspberry Pi used this size but moved on the to MicroSD card size with the B+ 512 version. A Raspberry Pi 2 and 3 uses a MicroSD Card format. Micro SD cards are commonly used in cell phones and other small electronics that need a very small storage device.
It should be a Class 10 micro SD card:
How fast an SD card can move data is rated by a class number from 2-10. With 2 being the slowest and 10 being the highest.
An SD Card with a class rating of 2 is good for taking pictures and storing them since there is no need to transfer large amounts of data quickly. For this reason, class 2 SD cards are often used in digital camera.
Class 10 SD cards are used in video equipment since they can transfer data quickly with no buffering.
A Raspberry Pi basically uses a MicroSD card as a hard drive and to store any information. For this reason, having a class 10 MicroSD card in your Raspberry Pi is very much recommended. There’s also a separate, even faster category called UHS Class 1 (for Ultra High Speed), often both are used. If a UHS classification is used then get UHS class 1.
Since the SD card holds all the information to run a Raspberry Pi from the operating system to applications very small SD cards are simply not reasonable even if they work with a RasPi.
Most installs use an 8GB capacity microSD card but things can move quickly with software, so getting a larger SD card is recommended. The largest sized micro SD card a Raspberry Pi can use is listed as 32 GB although some forums have people talking about using a 64 GB SD card with no problems.
If you are just starting out stick with an 8-32 GB sized microSD card.
One last note is that many people in the RasPi community recommend getting an SD card that utilises Wear Leveling.
Wear levelling is when the same spot on an SD card is not written over when there is free space to write to. This extends the life of an SD card since multiple spots are written to and from instead of the same open spot over and over again.
Extend your devices with a card from the EVO-Plus series. The EVO Plus provides fast read and write speeds.

The Integral 32GB UltimaPRO V30 Premium Micro SD card, offer superior, super-fast read and write speeds – ensuring that you can record high-definition video and take burst mode photos with confidence. With ultra-fast read and write speeds of up to 100MB/s and 70MB/s, respectively, you can be confident that Integrals premium cards are the perfect partner for your device. Additionally, rated with A1 App Performance Specification, and high IOPS this memory card ensures the best performance for your Raspberry Pi.
Kingston’s Industrial Temperature microSD UHS-I has an operating temperature rating of -40°C to 85°C, making it suitable for harsh environments. Its high operating temperature rating means it stands up to extreme heat in the desert and in test and measurement situations where standard microSD cards may fail, while its low operating temperature rating allows for use in below freezing weather, where equipment may be left outside for extended periods of time. Its high insertion rating is ideal for applications in which the card will be frequently accessed and removed from host devices, and its MLC NAND allows for large amounts of data to be written to the card.
