I've tested half a dozen different SEKC Micro SD cards in devices ranging from portable handheld computers to cameras and game consoles and the card is not only is it very fast to read and write, but it's cheap and as reliable as any Samsung or SanDisk card on the market. Luckily it's not a brand as these cards are very well promoted in Taiwan and if you're lucky you'll even see some with internal SanDisk controllers. These cards cost almost half the price of your premium Samsung SD cards but are just as reliable and fast, so my last order was for 4 of the same 512GB micro SD cards that I've been using for 4 months now. . I hope the brand gets better known (or keeps it secret so prices stay as low as they are now ;-). I believe this brand is on par with SanDisk and Samsung.
