Recently at Mobile World Congress 2018, Western Digital announced its newest microSDXC card that it touts as “the world’s fastest UHS-I flash memory card” – the 400GB SanDisk Extreme UHS-I microSDXC card.
The card features super-fast read speeds up to 160MB/s, write speeds up to 90MB/s, UHS Speed Class 3 (U3) rating, and a Video Speed Class 30 (V30) rating, which means this card lets you capture uninterrupted 4k Ultra HD video.
All SanDisk Extreme cards are shockproof, temperature-proof, waterproof, and X-ray-proof, making them ideal for all conditions.
Although I use SanDisk Compact Flash cards as my primary memory card, I always have a SanDisk SD card in my camera’s second slot and in my second camera – they’re the only cards I have never had a problem with.
Pricing and availability are not listed yet, rumors say that it will be in the $300 price range.
