Western Digital has unveiled a 400GB microSD card, which it claims is the biggest on the market at the IFA 2017 consumer electronics show.
The 400GB SanDisk Ultra microSDXC UHS-1 card is twice the capacity of the 200GB version that broke the record just two years ago.
"We continue to push technology boundaries and transform the way consumers use their mobile devices," said Sven Rathjen, vice president, product marketing, Western Digital.
"By focusing on achieving new technology milestones, we enable consumers to keep up with their mobile-centric lifestyles with storage solutions they trust."
The product is aimed at Android phone and tablet users, especially those taking advantage of Android Marshmallow and the ability to merge together multiple storage sources into a single storage pool.
"Mobile devices have become the epicentre of our lives, and consumers are now accustomed to using their smartphones for anything from entertainment to business," said Jeff Janukowicz, research vice president, IDC.
"We are collecting and sharing massive amounts of data on smartphones, drones, tablets, PCs, laptops and more. We anticipate that storage needs will only continue to grow as people continue to expect more sophisticated features on their devices and desire higher quality content."
IDC estimates that 150 billion apps will be downloaded this year alone. But while many devices, even on Android, don't have an SD slot, the vast majority will need more and more storage to make the most of pace of software development. SD cards and readers could be a good portable, non-cloud solution.
With transfer speeds averaging 100MB/s, the new release is capable of running 4K video and transferring up to 1,200 photos per minute.
Sandisk told us that it has always made a point of only delivering at capacities where the technology allows them to not interfere with the temperature or performance of the host device, hence not simply doubling the capacity on a yearly basis, even when it is technically possible.
Offering a 10-year limited warranty, the 400GB card is available directly from Sandisk and other retailers for £224.99.
