The World's Highest-Capacity microSD Card Can Now Be Yours

With SanDisk's 400GB card, you don't have to worry about your storage problems anymore.

SanDisk is bringing the microSD card game to new heights. Yesterday at the IFA consumer electronics tradeshow, the company unveiled what is now the world's highest capacity microSD card. At 400GB, the SanDisk Ultra microSDXC UHS-I card has 144GB more storage than any other microSD card on the market.

The new card is ridiculously fast. It supports 100MB read speed, A1 app performance, and UHS Speed Class 1. That's a lot of storage power for such a tiny card. That translates to about 1,200 photos per minute.  It’s also rated for full 1080p video.


Sven Rathjen, VP of product market at SanDisk's parent company Western Digital, credits the achievement to striving to be atop the market. “By focusing on achieving new technology milestones," he explained, "we enable consumers to keep up with their mobile-centric lifestyles with storage solutions they trust.”

Wired went ahead and crushed some numbers to help consumers realize just what this baby is capable of and released a pretty funny list of items you could store on it, including:

  • 40 hours of 1080p home video
  • 105 copies of The Lion King in HD
  • 62 copies of Sports Night: Season 1 in SD
  • 6,825 copies of Taylor Swift’s “Look What You Made Me Do” (video)
  • 54,794 copies of Taylor Swift’s “Look What You Made Me Do” (mp3)
  • 250,000 GIFs of Minions laughing in the snow
  • 4,683 episodes of the Comedy Bang Bang podcast (they've made 506 so far)
  • 70,633 copies of the King James Bible
  • 551,724 copies of The Bible for Dummies®, Mini Edition
  • 67,796 photos taken with a Samsung Galaxy S7
  • 80,000,000 New York Times Sunday crossword puzzles
  • Almost two-thirds of the entire GeoCities archive

if this card is fast enough to handle 4k raw...which i'm not sure that it is..(yet)... you may see camera and recorder designs changing smaller, cheaper, eliminating SSD's ... pretty cool !!

Yes, the write speed is considerably lower than the 100MB/s read speed. The card is suitable for phone level 1080p video capture. Not 4k, raw or prores judging by their product page.

that stinks, so this card is aimed at the real serious phone cinematographer?

Or the teens that never delete their camera roll. If anything, it does seem more aimed to photography, and phones.

The capacity is becoming a "no problem" nowadays.
Anyway, 4K is to be included.
