SanDisk has released the ‘world’s first’ 400GB microSD (SDXC) card. It is class 10, which means it can be used for full HD (1080p) video recording, but not necessarily 4K recording, as it has a write speed of only 10 MB/s. 10 MB/s isn’t slow. It’s just not enough for 4K.

A write speed of 10MB/s is actually faster than typical microSD cards, but if you want an SD card for 4K video recording, there are cards that achieve write speeds up to 90MB/s like the SanDisk Extreme Pro 46GB (SDSDXXG-064G-GN4IN).

For longer movies that happen to be under 1080p, the 400GB one is on Amazon, but it may take up to 4 weeks to ship at the moment.

What Can You Do With A 400GB microSD Card?

You can store over 66,000 6MB songs (in the MP3 format), or up twice as many songs if stored in the Ogg format at the same quality setting.

Or you could store 40,000 10MB high-resolution photos (5,000 pixels wide).
