256GB Micro SD Card, Amplim Extreme High Speed MicroSD Memory Plus Adapter, MicroSDXC SDXC V30 A1 U3 Class 10 UHS-I TF Nintendo-Switch, GoPro Hero, Surface, Phone Galaxy, Camera Security Cam, Tablet

I recently tested a number of 16 and 32gb cards for use in a Raspberry Pi application. The tests were performed in CrystalDiskMark 7.0 using the "Real World" profile. Although this card showed a super-fast sequential read speed of 88MB/s and an acceptable 4k random read speed of 9.7MB/s, its write speed of 10.5MB/s sequential and 2.9MB/s random barely qualifies it as a Class 10, much less an A1 card.If you're looking for a fast inexpensive Micro SD, have a look at this one: https://smile.amazon.com/gp/product/B0834R2C6T/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1For about the same cost per card, you get twice the capacity and about 4 times the speed.

Best price for a Class 10 U3 micro card I could find. Well packaged including SD adapter, if you need it. Im Buying another one !!

Ordered for my grandson for his Fire7. He was very quickly impressed with the additional space available to him.

The product came quickly and package was secure. My kyocera duro pro 2 accepted it quickly and that was great. I have not had any issues so what more could anyone want. Thank you

Good price, arrived promptly, packaged well.Dropped it into my HP Chromebook and it immediately appeared as a local (removeable) storage device.Hard drive? What hard drive? Who needs a hard drive?Tested capacity, 100%. What's not to like?Used the second card for my CHROME OS recovery media.Good stuff.

It's a refurbished tablet bought for a specific purpose and I wanted to have extra storage space - the micro SD card is perfect - now as a "permanent" drive on the tablet I have the extra room I wanted for it. Because it came with two SD cards, I also bought a micro usb hub for the tablet should I need to connect anything (as it doesn't have a usb port) which also has a micro SD space. I plugged the hub in, added the micro SD card and the tablet read the spare disk mounted on the hub. More extra space if needed or possibly a good way to transfer between my laptop and the tablet if it would take too long through a bluetooth connection. Anyway, the micro SD cards work perfectly.

Great buy if you go thru MICRO cards like this house does. We use them in our phones, tablets, cameras, Bluetooth headphones for tailored music lists and our security cameras. I like that the MICRO card holder also comes with so I can edit fotos on my laptop in the reader. We also use larger cards, but this is a the perfect price and size so a lot of data or fotos are not lost if the card becomes corrupt or needs to be replaced.

These are some of the best Micro SD cards I have used for pictures and videos. The write speed helps to prevent lag. I would recommend them to anyone needing a memory card for video's, pictures or music.
