An entire terabyte of data can now fit on a microSD card — and now data can be recorded as fast as 160MB per second. On Monday, February 25, Western Digital announced the 1TB SanDisk Extreme UHS-I microSDXC card during Mobile World Congress. While the new microSD is not the first to reach that 1TB capacity, the company says the new card is the fastest 1 TB UHS-1 microSD card yet. Micron also launched a 1TB card, joining Lexar’s 1 TB announced earlier this year.
