In a simpler format, here are my picks for the best microSD cards on the market for use with the Raspberry Pi: The SanDisk Extreme and Samsung Pro+ are also worthy options, but both cost slightly more than the Evo+, and offer slightly less performance overall. Since the Pi's microSD I/O is often the major bottleneck (especially now that the onboard LAN and WiFi have upped their bandwidth by at least 2x over the previous generation), it's important to get every bit of speed out of the card that runs the OS as is possible. Just as with the model 2 B and model 3 B, the Samsung Evo+ outshines the rest of the field in 4K random read and random write-two of the most important metrics for common Raspberry Pi use cases. Without further ado, here are the latest results, tested on a Raspberry Pi model 3 B+: One of the highest-impact upgrades you can perform to increase Raspberry Pi performance is to buy the fastest possible microSD card-especially for applications where you need to do a lot of random reads and writes.Īs part of my work on a comprehensive review of the Raspberry Pi model 3 B+, I decided to re-run all the benchmarks for all the Samsung and SanDisk cards (the rest, from Sony, Toshiba, Lexar, and no-name brands were so slow for Pi usage as to not warrant any testing at all!). In the intervening three years, the marketplace hasn't changed a ton, but there have been two new revisions to the Raspberry Pi (the model 3 B and just-released model 3 B+). hard drives), I performed only sequential read/write tests, out of curiosity also checking how the cards deal with small data blocks of 32 and 4KB.Back in 2015, I wrote a popular post comparing the performance of a number of microSD cards when used with the Raspberry Pi. Due to the way memory cards are being used (different loads than e.g. The program offers a little more possibilities of testing. It is worth adding that for the testing purpose I used the built-in card reader in my Dell laptop, which could have resulted in getting lower values in case of both cards. These are values only 11% and 12.5% less than the MAXIMUM declared read / write according to the manufacturer’s data. The results of H2 test show that Angelbirds cards cope 5.53% better with reading and slightly better with writing – by 0.82%.
