Given my experience with microSD cards, I wonder how reliable that device is. Is it even possible to write the full 1 terabyte successfully with a good chance?

Strange, I have had dozens of USB sticks failing, but no microSD issue. Even those with the most writes (in dashcams) have been going strong for years now.

  I wonder if this is less a problem with the media, and more with unstable supply of power to the devices. Perhaps relevantly, SDHC and SDXC support two voltage modes.

I immediately had a similar question, and have been wondering about why... SanDisk was very reputable for memory cards, such as their CF cards preferred by professional photographers, but (perhaps because of that) SanDisk was the first target I recall for eBay counterfeits. The counterfeits were sophisticated, including retail packaging, and I've heard of it also getting into the supply chains of some retailers. I wonder whether this early counterfeiting (even before problems on Amazon) ruined the market for reliable memory cards, and everyone switched to competing primarily on size, speed, and price. (If you're going to get lots of bad reviews anyway, due to counterfeits, you might not want to invest substantially in high quality that nevertheless only reduces bad reviews and RMAs a negligible amount.)

Sandisk Extreme cards are very reliable within their (relatively limited) write endurance. If you buy a Sandisk Extreme card from Amazon, it probably isn't a Sandisk Extreme card.

  I've been using a Sandisk Extreme 64GB card in my GoPro daily for months without an issue. I've had maybe one or two videos in that whole time that had any issue at all, and even then, VLC was able to play everything other than a second or two around the problem.

  What do you mean by "probably"? Are you saying that nearly all Sandisk Extreme cards on Amazon are counterfeit? Just 50%? Either way it's an amazing claim and I'd like to read the supporting material.

    In a recent lawsuit, Apple claimed that 90% of the Apple-branded Lightning cables they bought on Amazon were counterfeit. Amazon clearly have a grave counterfeit problem. I don't know the exact percentage of fake Sandisk cards, but I'd rather not play the lottery with my data. Adorama and B&H have trustworthy supply chains and fair prices. https://www.engadget.com/2016/10/20/apple-lawsuit-amazon-chargers-fake/ https://www.engadget.com/2016/10/20/apple-lawsuit-amazon-cha...

      Since then Amazon has become an Apple Authorized Reseller so maybe there's more incentive to crack down on Apple products, at least.

  It's funny how Samsung cards from Amazon are green but they're red if you get them from anywhere else. It's almost like Samsung doesn't want Amazon counter-fitters diluting their brand on other sites.

My first thought, too. My 120G SD card failed pretty quickly, causing me a lot of time to get my phone apps back to a working state. I ended up throwing it away and buying a new phone with more memory. It was that costly to me (in time).

The way this is going what we really need is a new card format with some kind of a controller inside that can do error correction and other basic stuff. Really just turn the card into a mini SSD.
