    I tested the card when it arrived today and the capacity is correct. However here are the read/writes speeds after repeated tests:

    Warning: Only 60803 of 60874 MByte tested.
    Test finished without errors.
    You can now delete the test files *.h2w or verify them again.
    Writing speed: 81.9 MByte/s
    Reading speed: 89.1 MByte/s
    H2testw v1.4

    I am aware it says “up to 170MB/s” however this is pretty far from it, isn’t it? It even says the same thing on the card, it’s not like it’s a typo on the Amazon page. Why???

    Sandisk box came opened. Would have been much happier to receive a sealed package from manufacturer. Makes me doubt the authenticity of the item. Seems to work ok and have the specified capacity. Nothing like as fast as I expected and soon slows to a stop on burst shooting. Not convinced it’s genuine thanks to the open box so only one star.

    Doesnt work in slot 1 of Sony A7III and reportedly other Sony cameras. Apparently an issue with the card not the camera? Works in slot 2 though. Any 64Gb card ending with batch no 838G is affected. Other sizes have other batch number issues as well. Plenty of data on the internet about this, wish i had read it first but never had an issue with Sandisk Extreme Pro cards before.

    I bought two of these cards to use in my Panasonic Lumix G9 and G80 cameras, where they appear to work fine (though they are no faster than my previous gold Extreme cards). However, they are proving to be extremely unreliable when inserted into my (late 2015) iMac’s built-in card reader. Sometimes they work (though again, the read speed is no faster than the older cards), but a lot of the time they don’t. They mount fine, but the image files are either absent, or they start off present and then disappear from the folders or can’t be read. Fortunately, the files are actually still there, and by putting the card back in the camera and downloading over USB I was able to read them. But because of this, I don’t 100% trust them, and will only use them in my G9 with an Extreme card in the second slot as backup.

    These cards have also had issues with some Sony cameras (see other reviews) which leads me to believe there is a particular problem with the ones designated 170MB/s.

    I have confirmed…

    I’ve used SanDisk SDHC cards for ages and always found them to be reliable (famous last words?) and the Extreme Pro card’s speed makes it ideal for fast burst photography and 4K video.

    I only ever use 32GB cards (I have half a dozen of them!) because, although their content is regularly backed up to memory sticks or hard drives, I’d rather risk losing only that amount of data than that on one of the larger capacity cards. I can’t even begin to imagine what I’d do if a 512GB card crashed!

    Two 32GB cards work out slightly cheaper per gigabyte than one 64GB too (59p compared to 61p). However, it has to be admitted that the larger cards beat them both on price (the 512GB card is around 46p per gigabyte).

    I’ve always opted for SanDisk Extreme Pro SD cards because I’ve found they provide me exactly what I need for my camera.

    1. Good writing speed for photography and uploading to PC
    2. Enough storage size for a good price.
    3. I feel safer using this card, it seems based on my experience with other brands that there’s a lower chance of SanDisk Extreme Pro cards malfunctioning.
    4. It also looks nice (I don’t know if this is something people care about, but I like it)

    1. I can’t comment on tech support, as I haven’t had to use it.
    2. Writing speed not 170MB/s (so the described speed actually refers to the read speed, but if you want speeds like this, you have to be willing to pay loads more, no matter the brand. Write speed is still fast enough for all the photos and videos I’ve ever had to shoot).

    Review for: SanDisk Extreme PRO 128 GB SDXC Memory Card (170MB/s)
    Using inside a very good camera and it copes with 4K 50fps vide nicely. Read and write speeds cope with the 4K video and also writing 30MB rawfiles in high speed bursts without a flutter.

    Received a counterfeit card. Speeds were ~11MB/s write/read nowhere near advertised and widely tested ~90MB/s. Checked on two laptops, my old Sandisk Ultra 80MB/s runs at ~30MB/s write & ~50MB/s read (well I don’t have the fastest reader on the planet, but it’s not an excuse for 11MB/s).

    Tested both on synthetic tests and real life tests.

    Print quality of the label and font details looked rather dodgy at times. Returned.
