Blazingly fast 400GB micro SDXC card in UHS-1 Interface!
Reviewed in the United States on November 30, 2018
Speed and storage capacity was very impressive in UHS-1 interface. It's compatible with most devices that supports micro SDXC with UHS-1 such as smsrtphones, tablets, drones, Nintendo Switch, cameras, you name it. It comes with 170MB/s Read while 90MB/s Write. Keep in mind that storage and performance may vary depending on host device. For instance, installing 400GB micro SDXC card reports storage capacity as 366GB due to binary format from operating system, though micro SDXC was stored in 400GB via decimal format as advertised. In addition, I have also tested on my Nintendo Switch, storage capacity still reports as 366GB due to binary format which there's nothing you can do due to binary format from operating system. As far as performance goes, I was able to record 4k footage no problem on my Samsung Galaxy S9+ Android Smartphone at either 30fps or 60fps with no frame drop, no degredation, image quality wise looks clear, and read/write performance was consistent too.
170MB/s Read & 90MB/s Write, thanks to its proprietary Western Digital technology, in collaboration with SanDisk

Coming from Samsung Pro 64GB micro SDXC, it was massively a huge upgrade to jump from 64GB - 400GB with blazingly fast performance in UHS-1 interface. I did ordered from the seller named Fineline Trading on Amazon US and was fulfilled by Amazon US. From that, it took 2 days to ship from Oregon to California via USPS, and finally was delivered to my mail locker from USPS. The package was in like envelope bag or whatnot. As a result, the package was intact, no bent, no scratch, no damage, no nothing. But overall, I'm very happy with my purchase for an upgrade. If you're looking for new micro SDXC card UHS-1 with faster performance & capacity, then I recommend SanDisk Extreme Pro 400GB UHS-1 micro SDXC card including adapter.
