I have had defective XQD cards from Lexar and SanDisk and the manufacturers replaced the ones I mailed to them after they could verify that they had defects. Very different experience with Delkin when one of their Black CFexpress cards had bad sectors. I emailed a copy of the invoice and photos of the front and back of the card and they initiated a replacement that same day.
Some takeaways for me are that Delkin is a good company to support and that I should be using smaller capacity cards for still shooting and that I need to go back to fully testsing my cards before putting them to use. I had a defective CF card and was shooting a wedding with the D3 and there were 3 files that were corrupted. No "money shots" but still a concern. After that I started loading my a new card to capacity and then moving the files from the card to a computer and then opening all the files with a program that would create the screen image from the Raw file and not simply grab the embedded JPG image. It becomes very easy to see if there is a bad section of the card with this process and I only have done this with new cards that I will put in to use. I can see with an important trip that a similar level of certainty that a card is defect free is important.
In my research I also learned that there are compatibilty issues with third party USB 3.1 G2 boards and my ProGrade CFexpress card reader. At least for ASMedia chipsets there are not compliant with PCIe specification 2 requiring PCIe lane negotiation. My card using this chipset would cause the computer to stall while transferring files.
