Micron has unveiled the world’s highest power MicroSD cardi400, with storage space up to 1.5TB, 50% more than the former champion, C200.
The semiconductor giant reached that power using its 176-level 3D NAND technology (which was used SSD) And will target the enterprise market, especially those related to end-to-end video storage. In other words, don’t expect the card to be cheap or easy to source, especially since it’s designed to handle five years of uninterrupted 24×7 high-quality recording and a huge MTBF of two million hours.
No details are given about its effectiveness, but it is clearly an industry-grade product – as opposed to the C200 – which means it has the potential to be written and tolerant at the top of the spectrum. The C200 uses a 96-layer 3D NAND technology and the i400 (also available in smaller capacities like 64GB) may have some extra capabilities for wear leveling.
Analysis: What’s next for microSD?
So far, Silicon Power, Lexar, Sandisk, Teamgroup And PNY Kingston and Samsung have remained silent on the sidelines.
In most cases, Cloud storage, Cheap bandwidth and ubiquitous high-speed connectivity High-capacity, high-performance local storage has become a thing of the past. This is one of the reasons why most high-end smartphones no longer offer removable storage.
So, will others follow Micron’s steps with microSD cards larger than 1TB? Most likely, however, they will not come cheap in the shrinking market.
One feature that it didn’t make on the i400 is SD Express, High-speed technology that can speed up data transfer at 4GBps. The problem is that this is usually a chicken-and-egg scenario where reader / compatible devices are not readily available to justify a significant increase in material costs.
