Frequently Asked Questions (FAQ)

Is this card compatible with Raspberry Pi 4?
Yes, it is perfectly compatible and meets the A1 spec recommended for running the Raspberry Pi OS.
Will this work with Arduino modules like the SD shield?
Yes, but you must format the card to FAT32 first, as Arduino libraries often do not support the default exFAT file system of 64GB cards.
Why does my computer show only 59GB instead of 64GB?
This is the difference between decimal (1000MB = 1GB), used by marketing, and binary (1024MB = 1GB), used by computers. The card is full capacity.
۔
Is this a genuine SanDisk product?
Absolutely. We source only from authorised distributors. You can verify it using the SanDisk verification app or sequential write tests.
What does "A1" mean on the card?
A1 stands for Application Performance Class 1. It guarantees minimum random read/write speeds, which is critical for running apps and operating systems smoothly.
Can I use this in my DSLR camera?
Yes, the included adapter allows it to fit standard SD slots, and the speed is sufficient for Full HD video recording.
Is it pre-loaded with NOOBS or Raspberry Pi OS?
No, the card is sold blank. You will need to flash your desired operating system onto it.
Does this card support 4K video recording?
It supports Full HD (1080p). For high-bitrate 4K video, we recommend the SanDisk Extreme series (U3 rated).
۔ What is the maximum read speed?
The card is rated for up to 140MB/s read speeds with compatible UHS-I card readers.
