SanDisk Extreme 400 GB microSDXC Memory Card + SD Adapter with A2 App Performance + Rescue Pro Deluxe, Up to 160 MB/s, Class 10, UHS-I, U3, V30, Red/Gold

Ordered one of these cards in 400G on Amazons limited deals which I couldn't pass up. Unfortunately the first card was completely d.o.a. The card couldn't be seen, neither as a standard card or with the adapter provided, even checked using other readers and adapters but no luck. Chkdsk couldn't see it at all and it would hang up some other devices I used to test. It was annoying but these things happen. Amazon were very quick to organize and send a replacement which arrived two days later. Second card worked perfectly so all was good and with limited inconvenience.

Just put it in, no formatting. As the Htc 10 is great for music even 24 bit music and films it was a strong temptation. I also got the 128 gb extreme a2 which I had no problems with. Though the Htc 10 reads the card storage a little higher it is not a problem. A2 is a new technology made by sandisk and western digital. You can buy cheaper but you get limited use and eventually the card loses the ability to write onto or be formatted, though leaving it as unencrpted on the Htc 10. Though many people use online music but off line music, films and books is nice to have. Also I use extreme cards in my car cams and they are still working after months of use.

having different reviews i was abit sceptical but i needed more space and it was cheap. more than 3 months, good speed and effective storage. will definatelyt recommend for others to buy.

Works fine

Bought for the nintendo switch as we quickly ran out of space with our 128GB. This was on offer so it was a great buy and works like a charm (side note if you buy for the same reason - format this on the switch and redownload all the games as save data is on the switch - wasted so much time trying to transfer and it doesnt work propperly). All in all a great card

It works on my Huawei 2 Lite and my Xiaomi 11 5G. Swapping from my old microSD to this was a life saver for me. When I bought a new phone I just took it out of the old Huawei and slipped it in the new Xiaomi 11. No problems so far.

Great storage size for an SD card which is inherently an expensive way to buy storage. The price was good for what it is. There isn't really anything I can say about presentation - it's a plastic storage card!

First card doesnt work. Replacement doesnt work either. (Other cards - diff capacities and brands - work fine on my devices) Looks like a defective batch of this model. Refund is 5-7 business days after return is received.

今のところトラブル等全くなく、機能してくれていて大変助かる。

I get the sense that these are pretty variable and there are a number of bad cards out there. My 400GB card, however, is working fantastically well. It's currently more than half full of data that wrote really quickly, and my tablet recognized it and works with it super well. It's been exactly the solution for me to load my ebooks and comics onto the tablet so I can take my crazy collection with me everywhere.

Using it on my Surface Pro 7. Installed some apps on it and the apps work fine. Data transfer is fast. A very good value. Highly recommended for Surface Pro users. Just put it in and forget about it. 400GB extra storage!!
