Need A Serious Memory For 4K Video? Meet Sandisk’s 400GB microSD cards.
Stephan Jukic – February 28, 2018
4K video-capable cameras, camcorders and now even smartphone cams have seriously proliferated in recent years but memory for the massively data-hungry shooting format has been one hell of a problem for many of these devices. What this has meant in practical terms for many people is that, while it’s great to have so many phones and little cameras grabbing beautiful, HDR-mastered ultra HD footage, storing that video quickly becomes a pain in the ass.
Sandisk is one of the data companies working to fix this problem. They’ve been at these efforts for a while now and we’ve covered some of their previous storage products before, but their latest effort is distinctly impressive.
The new 400GB Extreme UHS-I microSDXC takes storing and moving all the pro or amateur 4K video you could want to create seriously indeed and the technology packed into the tiny microSD gadget actually tries to make the whole process behind that Easy. Needless to say, this is one crucial characteristic that many camera users can respect.
What the Extreme UHS-I microSDXC card offers is the already mentioned 400GB of solid storage space, meaning plenty of room for even fairly long 4K video recordings. On top of this it also backs these things up further by helping recording or movement of the video with a cool 160MB/s read speed and a more modest but robust 90MB/s write speed. These speeds and the memory itself are compatible with a majority of devices according to their maker and the new microSD card line comes with the A2 specification for 400IOPS read and 2000 IPS write speeds. This also happens to mean faster launching of apps from the memory device.
Yes, there are faster microSD cards available on the market but Sandisk has an ace up its sleeve with the Extreme UHS-I microSDXC in the fact that those other, faster cards are of the UHS-II type for the most part and thus nowhere near as compatible with most smartphone models as these UHS-I types. The new microSD cards have however had their speeds boosted higher than normal through Western Digital 3D NAND technology to make them faster still.
Other useful bonuses of the new memory card series include shockproof design, high or low temperature resistance, waterproofing and even X-ray proofing if that’s something you happen to need. Sandisk backs all these claims of hardiness up with internal test specs and such robust specs make the Extreme UHS-I microSDXC card line particularly useful for recording via drone, camera or even phone in more intense situations such as wildlife photography, underwater shooting and drone recording. If you don’t mind their cost you can however also just use them for even the most ordinary stuff on a lazy Sunday with your new iPhone 7S and its 4K camera though.
