New 1TeraByte (Yes, TeraByte) MicroSD Cards Launched

Both Micron and Western Digital’s SanDisk brand have announced at the Mobile World Congress that they are launching the first 1TB microSD cards.

A First

Up until now, companies haven’t been able to produce anything above 128GB, so the jump to a 1TB capacity card is a big jump that could mean less reliance on the Cloud for storage, and better performance from smartphones and other devices.


Micron Technology, Inc., the US global corporation based in Idaho has announced the launch of the c200 1TB microSDXC UHS-I card, an innovative removable MicroSD Card that boats a terabyte of A2 grade storage with V30 certification.  This should mean that although it can seriously ramp-up the performance of a smartphone, it could suitable for any number of devices and gadgets.  The new card uses an (up to) 100MB/s read-write rate, which means that it can support and can store up to 40 hours of 4K HDR video, thousands of 40MP+ photos, and mobile.

Micron reports that the new card leverages 96-layer 3D quad-level cell (QLC) NAND technology, thereby providing cost-effective storage for consumer electronic devices. 

The Micron website says that the new c200 1TB microSD card “gives consumers the freedom to capture, share, store and enjoy more content while supporting their mobile-centric lifestyles.”

When For Micron?

Micron can only say that the new MicroSD should be broadly available, sometime in Q2 2019.


Western Digital’s SanDisk Extreme “microSDXC™ UHS-I” MicroSD card is available in both 512GB and 1TB capacities, and can reach speeds up to 160mb/s with A2/V30.  It can be used in Android™ smartphones, action cameras and drones, and offers supports 4K UHD video recording, full HD video and high-resolution photos.

Also A2 rated, the card reads up to a reported 160MB/s, and writes up to 90MB/s, thereby providing fast app performance on smartphones.  Its fast read speeds should mean that users can save a lot of time e.g.when transferring high-resolution photos and video.

When For Sandisk?

Reports indicate that it will not be available until April, and as a guide, expect a price tag of $449.99 for the 1TB version, and $199.99 for the 512GB version.

What Does This Mean For Your Business?

The huge storage capacity and the speed of these new cards is, of course, good news in terms of versatility and flexibility, saving time, and requiring less reliance on moving and storing everything in the cloud. A card like this is, however, likely to set you back around £375 but you may decide that this is a price worth paying for the extra capacity, speed and convenience.

Although these two new cards are A2 standard, so are suitable for running applications, most microSD cards are slower in practice than stated in the tech spec, and most devices don’t try to run applications from SD cards.  Also, being removable cards, they can still be lost or stolen, and could, therefore, be a security/data security risk depending on what you have stored on them, not to mention the expense of having to buy another one. You may decide that a fast, standard microSD card is still good enough, and you’re prepared to still rely upon secure cloud storage for most things. 

It is also worth remembering that a new, super-fast SD Express standard, part of the wider SD 7.1 strategy, could soon be introduced, and could deliver read speeds of up to 985MB/s (if there were products that lived up to the standard).
