Raspberry Pi Models now have better WiFi bandwidth (802.11ac in Pi 3 B+) and an on-board LAN. Therefore, your Pi’s micro-SD I/O will be the most significant performance bottleneck.
Therefore, a fast Pi micro-SD card – with high 4K random read and 4K random write – will be a critical Pi performance upgrade, particularly for storing your Pi’s OS and the program memory.
However, the life of your Pi’s Micro-SD (either Micro-SDHC or the SDHC) is limited and some cheap cards have poor wear levelling.
Thus, between the excitement of running a Review of Pi model 3 B+, I undertook benchmark runs (with Raspberry Pi model 3 B+) for various MicroSD cards.
Note: Raspberry Pi 3 Model B & Model B+ are only compatible with Micro SD cards. However, you must format Micro SD larger than 32GB to FAT32.

Buyer’s Guide – Best SD Card for Raspberry Pi 3
What you MUST KNOW before Selecting your Raspberry Pi3
So, what role do the SD cards serve?
SD cards store data files and enable Raspberry Pi3 Software booting, and other such other functions in Orange Pi computers, or various small Linux Ports. In addition, consider purchasing a cooler and power supply for highest efficiency.
Raspberry Pi SD Cards Considerations
Considerations for Raspberry SD cards are speed, format, and physical size. Notably, cheap SD card lack wear leveling and thus some sections of the card gets written to over continually until they fail.
Therefore, if Raspberry Pi tries to write over the worn out area, despite other section being intact, it will fail immediately.
My key research question will be (1) will SD card capacity affect speed (2) Do original SD card perform better (3) are expensive SD cards have better performance.
Despite that all Raspberry Pi fits all Best SD Card for Raspberry Pi3, you should consider the following factors to decide the card to purchase for your raspberry pi3.
SD Class (Ranging from Class 1 to Class 10): Your card’s class will affect the transfer speed and storage of data. For example, class 5 cards will only allow 5 MB/s.
Further, you should not that the higher the class number implies that the SD card will perform better in your operation of raspberry pi3.
What is raspberry pi SD card capacity limit?
Micro SD storage capacity: Despite that you might only require only 4GB to install Raspbian Lite image, other installations are different. If you will need to install Raspbian or NOOBs, then your least SD card capacity in your Best SD Card for Raspberry Pi 3 will require to be 8GB.
Raspberry Pi 1B+, 2B, and 3B comes with microSDHC card slot and thus will only allow a maximum of 32GB size SD cards.
However, there are some SD cards that will function in the microSDXC cards slot which are larger than 32 GB.
Note that all SD cards larger than 32 GB will be formatted to exFAT filesystem, as noted by Raspberry Pi foundation, as opposed to the normal FAT32 filesystem.
Therefore, if you require to install NOOBS on SD cards larger than 32 GB, then the installation process will be harder, as outlined on the foundation page.
However, if you decide to utilize Raspbian, or another OS through writing a disk image on the SD card, you’ll not need to change the exFAT to favourable FAT32.
Writing the image of the disk will overwrite everything, including the SD card filesystem.
Consider Wear Leveling
Therefore, you will need to get SD cards that has wear leveling, in which when there is adequate free space, the write access will be distributed evenly.
The low-priced and counterfeit SD cards lack wear levelling. You will continually overwrite some regions of the SD Card, one without wear levelling, leading to increased abrasion in that area and failure of the SC Card.
Therefore, your Raspberry Pi3 will fail if it attempts to use the area that has been continually worn out, even though other SD Card areas are still intact.
Raspberry Pi, small single-board computers, were first designed to promote compute science education. However, the Best Raspberry Pi3 Kit on Amazon have now become popular among computer scientists, robotics enthusiasts, tinkerers, and kids.
