SanDisk’s New Extreme 400GB is the World’s Fastest UHS-I microSD Card
Western Digital has announced the new SanDisk Extreme 400GB UHS-I microSD, the world’s fastest-ever UHS-I microSD card.
Memory cards that are both spacious and speedy are becoming increasingly important as smartphone cameras become more advanced and are capable of capturing high-megapixel RAW photos and 4K-resolution videos.
This new SanDisk Extreme 400GB card has read speeds of up to 160MB/s and write speeds of up to 90MB/s. The read speed is over 50% faster than SanDisk’s current lineup of Extreme UHS-I microSD cards.
“The card is able to reach this unprecedented speed by leveraging Western Digital proprietary technology,” Western Digital says. “The card will also feature the A2 specification to help launch and load apps at blazing speeds.”
Western Digital says it’s also working on PCIe-enabled SD cards that will have even higher speeds for even more data-intensive camera features like 8K video and RAW continuous burst mode.
While pricing and availability for the new SanDisk Extreme 400GB UHS-I microSD have yet to be announced, there are murmurings that it will cost $300. The price of the existing Sandisk Ultra 400GB Micro SDXC UHS-I Card has also been dropped (perhaps temporarily) from $250 to $190.
Correction: An earlier version of this article stated that this memory card has become the world’s fastest microSD card. As commenters have pointed out below, it’s the world’s fastest UHS-I microSD card. We apologize for the error.
