    I purchased this while on sale and saved a bundle. I originally purchased it as additional extra storage for my business only tablet. I have since accuried an additional tablet and use this in the "extra" tablet. I will end up buying another smaller memory card for the extra tablet as it doesn't require this much extra space for the purposes I use this tablet. I will then have an extra memory card for my business tablet when the time comes that I fill my current memory card.

    Fast data transfer with 3.0 card-reader ONLY.

    I bought this to upgrade my Galaxy S7 memory card from 64gb to 128gb because I was almost out of memory. I had the data transferred to my computer and used a card-reader to transfer from the computer to the new card. It was EXTREMELY fast! Literally minutes to transfer 62gb of files! BUT, I am having problems transferring data to the memory card when it is in the phone using a USB connection to the computer. It may copy a few items, then totally freeze up. I have to 'safely' remove device and plug back in to get a few more files copied before freezing up. I gave up. SOLUTION... I have to remove the SD card from the phone and transfer files using a 3.0 card-reader. Instantly copied with no problems. I don't know if it's the phone that doesn't like the 128gb memory card or what. The memory card was formatted on my phone before putting any data on & was ejected and inserted properly. I still love SanDisk products & will probably upgrade to another one when the time comes.

    After doing a bunch of research on read/write speeds, I settled on this one from Best Buy that is fast enough to record massive 4k videos on my Galaxy s7. Not even a hitch or hiccup. This thing worked instantly after putting it in my S7. Very happy with it and it was drama free.
