Why Not All SD Cards are Created Equal


#1

If you are using SD cards in your end products, then I think this Element14 blog post is relevant. It discusses some of the differences between retail and industrial cards.

The Ultra96 will be shipping with a 16GB Delkin MLC Utility card. I will be testing out 64GB and 128GB versions as well. Newark has stock on many sizes if you want to experiment.

I got a 128GB Utility MLC card from Delkin and can verify that it successfully booted my Ultra96. I have a 1GB FAT32 primary boot partition, 7GB EXT4 secondary boot partition, and 120GB EXT4 third partition. It booted up fine, and I was able to fill the remaining 120GB with test files.

Here is the card that I tested:

I also have a 64GB MLC Utility card that I will test next.
