FakeFlashTest is not as thorough as H2testw, but it takes seconds to complete instead of hours and, in near all cases, catches fake cards as well. Also note that you can use the much faster FakeFlashTest tool to verify capacity as this writes and reads random sectors on the card from beginning to end. If it passes these tests you did not receive a fake and, rarely if you do, you can return them easily and for free via Amazon as long as they are fulfilled by Amazon, of course (it tells you, depending on who you choose as seller). Otherwise this is a great card for most large storage, fast access needs.Īs with all SD cards you buy, 3rd party or 1st, you should use H2testw to verify both the full capacity and read, write speeds of these cards once you receive them. If you're looking for security cam, dash cam or drone use, I'd suggest a different and less performant high endurance card that fits those environments ( such as these). These are also ideal for photographers and videographers at 4K resolution (and some 8K scenarios, but not extended burst captures at 8K). The 1TB version is available from two different sellers, both fulfilled by Amazon:īeing rated A2 with very fast read and write speeds as well as having a stellar warranty and reputation for lifespan, these would be ideal for a Steam Deck or Nintendo Switch, Android or Apple tablet or phone and other devices where large storage, application load and smooth running are paramount. The 512GB version is available shipped and fulfilled by Amazon: This is the all-time-low pricing for both of these cards according to Keepa. As these are both fulfilled by Amazon you have free and easy returns if there are any issues. Standard price for the 512GB version is usually between $80-$90 and for the 1TB it is usually between $225 and $240. The 512GB version is sold and fulfilled by Amazon for $75.00 and the 1TB is sold by 3rd party but fulfilled by Amazon for $158.00, $38.28 or 20% off.

Amazon is currently running good deals on the SanDisk Extreme 512GB and 1TB U3, A2, V30 microSDXC cards, the newer SDSQX AV editions with max 190 MB/s read speeds and max 130 MB/s write speeds (obtaining these maximum speeds requires a U B 3.x card reader).
