The Micron c200 is 1TB of microSD Beastly Data Storage
Micron, with the corporate office based in Boise Idaho, introduces the c200 microSD card with a data storage range from 128GB to 1TB. No that wasn’t a typo, One Terabyte of storage. The card was designed to address the demand around 4K video recording and playback.
The card has read speeds near 100MB/s and write speeds of near 95MB/s. The c200 card collection can reach these speeds because of Dynamic SLC cache; which is intelligent maintenance during idle time for sustained peak performance. The Micron microSD card uses the UHS-1 Speed Class 3 for capture and Video Speed Class 30 for support. Meaning to get these transfer rates, the host device must also be UHS-1 compliant.
In case you are wondering, the card uses Micron 98-layer 3D QLC NAND memory, which is cost effective for both consumers and commercial customers.
If you have an Android device, you can be even happier with the card meeting the Application Performance Class 2 specification which is built-in memory expansion for compatible Android devices.
The Application Performance Class 2 (A2) is defined by the Secure Digital (SD) Physical 6.0 specification. A2 makes SD memory cards higher performance devices than A1 devices by using functions of the Command Queuing and Cache framework. The Application Performance Class can be applied to UHS SDHC/SDXC Memory Card product family.
The table below compares the Application Performance Class 1 (A1) and Class 2 (A2) specification including Pictograph, the minimum average of random read/write IOPS (where IOPS means the number of 4KB read/write commands which could be executed per second), and the minimum sustained sequential write performance (MB/s). Of course these are theoretical conditions.
The Application Performance availability can be found in the card registery. It’s worth noting; the A2 performance is only available with an A2 supported host and an A2 supported card.
