Our company has a product that is being sold via channels. It uses SD cards for storage. Let me assure you, we have zero idea if our OEM uses good SD cards or the cheapest SD cards on a market that they can buy. We also test thousands of SD Cards to ensure that they work with our product should a user want to replace an SD Card. We acquire said SD Cards from "manufacturers" and all kinds of stores.

There is no rhyme or reason what works and what does not, what is fake and what is not. Apparently, we just had a 256GB no name, found on Alibaba SD card for $44 USD pass all the tests with a flying colors ( and go through about 100 full write/full read cycles ) while newest drop shipped from a "fulfillment" center 128Gb Samsung SD Card ( received via email directly to our Samsung contact ) end up being a 32Gb relabeled card.
