SanDisk develops new ultra-powerful micro SD cards for 14 hours of 4K Ultra HD video

If you’re a serious creator of 4K ultra HD video or an amateur who has LOTS of footage recording in a single session in mind, then SanDisk’s new Extreme 256GB microSD cards might just be the tool for you.

They can not only hold as much as a whopping 14 hours of 4K ultra HD video on a single card unit, but they also absolutely rock at data transfer with a read rate speed that manages 100Mbps and a write rate of 90Mbps.

The different possible uses for these monster cards are of course numerous when it comes to 4K recording. If you happen to own a 4K UHD drone like the Phantom 4 from DJI or maybe Yuneec’s Typhoon Q500, a single card can buy you literally days of flight time recording storage for these drones’ 4K cameras.

Then of course there’s field recording of said video from a 4K camera that takes the micro SD format. Whether it’s a mirrorless, camcorder or DSLR, the SanDisk Extreme card is the perfect long-term field shooting tool since it dramatically simplifies recording storage on the go.


None of this is to mention the monstrously great efficiency and storage capacity of the Extreme card if it were to be used for recording and storing mere Full HD digital video.

SanDisk has also released an “Ultra” microSD card with slightly less read/write power but the same storage capacity. The Ultra card is in fact aimed more at HD recording with its lower data transfer speeds and handles more than 24 hours of HD media.

Of course, none of these new cards are in any way cheap, as can be expected. The Extreme card with the 100Mbps read and 90Mbps write speeds will be hitting the shelves in the fall/winter of 2016 for $200 and the Ultra card for high intensity HD recording will go on sale in August for $150.

SanDisk is also claiming that both cards are waterproof, highly resistant to high temperatures and also both shockproof and even X-ray proof. These claims just add more weight to the field (or possibly deep space) shooting chops of the two new microSD cards.
