Samsung and LG have announced new flagship phones at this year's Mobile World Congress, and this time around you can plug a microSD card into either one. That makes now a pretty decent time for SanDisk to announce a new microSD UHS-II card with transfer speeds of up to 275MB/s (also, a dedicated USB Type C flash drive).

SanDisk's Extreme PRO microSD offers roughly three times the read speed of the company's current Extreme UHS-I microSD card, which can transfer data at 90MB/s. The new write speeds top off at 100MB/s. With this leap forward, SanDisk's tiny cards are now comparable to its full-sized Extreme PRO SD cards that can reach read speeds of 280MB/s.

The Extreme part of the name comes from this line being marketed as shockproof, temperature-proof, waterproof, and X-ray-proof. These new class 10 cards come in two sizes, 64GB and 128GB. SanDisk probably figures that if you're trying to move around data this fast, you're moving large files that would fill up 16GB or 32GB too quickly to be worth it. 64GB and 128GB both give you plenty of space for photos and enough room to record a decently long video or two.The smaller option goes for $179.99, while the other is $299.99.
