256GB Micro SD SDXC Memory Card High Speed Class 10 with Micro SD Adapter

Took a chance on this because it was sponsored by Amazon. It was advertised as "high speed". When I did a speed test, it was only writing at about 6mb/s. It does seem to have 256gb of storage. I am returning it to Amazon.

Mine was damaged. I was able to get around 70-ish GB out of it. At first I was worried. It's a common scam to have smaller SD cards (4GB or so) with micro controllers that just say they're larger to whatever machine they're plugged into. But I ran it through a verification program and sure enough it did appear to be a 256GB SD card. I ran it through another utility and found that all of lot of the sectors appeared to be there but many were just damaged -- and unevenly at that.Returned.Also since purchasing, the listed price has gone down considerably and the image has changed so I would'nt be surprised is the new cards they're displaying are scam cards, not just damaged.

Purchased 2 of these for my mp3 player. When I try to download ~200gb of music, the card swould say it downloaded everything, then when it was put into the player, most of it wouldn’t be read and when I put them back into my computer, they would be corrupted. That’s only when the cards would download. The majority of the time the cards would stop downloading altogether and nothing could be deleted until I wiped them completely and start the process again. I’ve tried everything on my side to get these cards to work and I just can’t. The discription read that they’re fast and couldn’t be farther from the truth. They were so slow that I thought that that could have been the reason that they didn’t work. A complete waste of money. If you want a good card, save a little more money for a Sandisk.

Arrived on time. Put where I didn’t find till next day. UPS issue. But installed in my Samsung Tablet was a learning curve to move my photos to the chip. Great value.

purchased for a nintendo switch, barely works. either it's much smaller than advertised or just not compatible.

Used this item and found it isn't 256 GB like the add says, loss tons of pictures and then the card fell apart!, DON'T BUY THIS CRAP! AMAZON NEEDS A QUALITY ASSURANCE FROM THESE VENDORS.

Sd card is a fake. Wouldnt load on my switch. Games wouldnt start. Verified with pc program that it's falsely saying its 256gb when it's not.

It looks like this is a fake SDXC micro SD card. As stated on other reviews, it is NOT high speed and it is NOT compatible with Nintendo Switch. DO NOT buy.
