IFA 2017 | SanDisk intros the world's largest microSD card to date

Memory cards for mobile phones have come a long way in just a few years, and the latest microSD card by SanDisk reminds us of this fact. Three years ago, SanDisk introduced a "record-breaking" 128 GB Ultra microSDXC. Just one year later, they increased the capacity of this fingernail-sized memory card to 200 GB. Now, the 400 GB SanDisk Ultra microSDXC card is ready to hit the market.

Advertised as an ideal choice for Android-powered smartphones and tablets, the new microSD card by SanDisk meets the requirements of the A1 App Performance Class specification. According to this performance standard, the new SanDisk Ultra microSDXC card must offer a random read/write performance of at least 1,500/500 IOPS and a sustained sequential speed of 10 MB/s. The official product page mentions a data read performance value of "up to 100 MB/s" and three video speed standards: C10, U1, and A1.

The 400 GB SanDisk Ultra microSDXC memory card will hit the market soon and has a MSRP of US$249.99. If this seems expensive, one last thing should be taken into account before deciding to skip the buy or not - this microSD card comes covered by a ten-year limited warranty and can handle water, shocks, X-rays, and temperature changes.
