Toshiba UHS-II SD Memory Card Review

Toshiba UHS-II SD Memory Card ReviewToshiba SD memory card were hard to find for a while and when you could find them they were way over priced. The company was in limbo and there was a lot of uncertainty with the brand. That doesn’t mean the Toshiba UHS-II memory cards are not amazing. They are often the best performing cards among those that I test, even though they are rated only at 260MB/s. Best of all they are now easy to find on Amazon and are priced very competitively.


Toshiba UHS-II Memory Card Sizes

The Toshiba UHS-II SD memory cards can be found in four sizes – 16GB, 32GB, 64GB and 128GB. As with all SDHC memory card, 32GB and smaller will use a 32-bit file structure and record with a fat32 file format, which caps your file sizes at 4GB. 64GB and above SDXC memory cards use exFat, which is a 64-bit file system. But there is more to memory cards than just SDXC and SDHC, there are also different speed classes which you can learn about in this guide to finding the best memory cards.

In-camera tests almost always results in the Toshiba card being in the top three fastest UHS-II cards with supported cameras.
