Why Not All SD Cards are Created Equal

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 new Ultra96 will be shipping with a Delkin MLC Utility card. Newark has stock on many sizes if you want to experiment.

Re: Why Not All SD Cards are Created Equal

The Ultra96 kit ships with a Delkin MLC Utility 16GB card. 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.

 

This is the particular card that I used:

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