SanDisk has just introduced its newest microSD card and it's a 400GB one. Yep, no mistake it the numbers: this just happens to be the largest-capacity microSD card available on the market, and it comes at a hefty price, as you'd expect.
The new 400GB SanDisk microSD card costs a whopping $250. Up until now, Samsung's 256GB microSD card was the biggest one available, and it is currently sold for around $150 on Amazon in the United States.
In terms of transfer speeds, the new 400 gig SanDisk card can reach up to 100MB/s for file transfers and goes as SDXC UHS-I class of a card. It is rated as App Performance Class A1, a rating that signifies that the card can run apps as well. And usually this is phone makers number one concern with external cards: they are often slower than built-in memory. That is the number one reason why companies like Apple with its iPhones and Google with its Pixel phones does not include the option for an external microSD card. It could simply slow down the phone.
