What brand would you trust the most, for SSDs and for SD cards?

There's only four flash manufacturers: Samsung, Micron, SK Hynix and SanDisk/Kioxia. All of them have had problems over the years. All of them will change the internals of products without changing SKUs or anything visible to the consumer. You best bet is: - Buy a variety of manufacturers and SKUs - Create backups regularly and test your restores

  Also, always run perf tests (especially using large writes - preferably up to the capacity of the drive!) for any drive that it is important 'you got what you paid for'. The number of counterfeit, badly designed to the point of defective, or DOA SD Cards and SSD drives I've seen over the last few years is crazy. I literally won't even buy USB sticks anymore. The last time I tried, all 5 different makes/models I tried were so dysfunctional they were useless. Literally unfit for purpose. Major brands too!

    Did you buy in person, or in an online marketplace (ex. Amazon)? I only buy thumb drives at physical stores to try and avoid outright counterfeits.

      Both. A lot (all?) recent USB sticks have terrible thermal design, and will throttle seemingly arbitrarily to very low speeds under sustained load. Like 2.5MB/s type speeds. They seem like they were made to to theoretically exist for the market niche, but no one expected them to actually be used by anyone who paid any attention at all. Same for ones bought in big box stores as Amazon or the like. Name brand or random brand. A lot of less expensive 2.5+ Gig Ethernet dongles do the same. Good performance for 5-10 seconds, then abysmal. I switched to SD cards, and at least the good brands of those had decent and predictable performance (50-75MB/s sustained for the same price point). They were also a lot cheaper in general for the capacity.
