Micron has unveiled the world’s highest-capacity microSD card, the i400, with space for storing of as much as 1.5TB, 50% greater than the previous champion, the C200.
The semiconductor big reached that capability by utilizing its 176-layer 3D NAND expertise (just like that utilized in SSDs) and can goal the enterprise market, particularly something that has to do with video storage on the edge. In different phrases, don’t anticipate the cardboard to be low cost or straightforward to supply, particularly as it’s designed to deal with 5 years of steady 24×7 high-quality recording and a whopping MTBF of two million hours.
No particulars have been offered about its efficiency, however that is clearly an industrial-grade product – not like the C200 – which implies that write and endurance are more likely to be on the prime finish of the spectrum. The C200 used a 96-layer 3D NAND expertise and the i400 (additionally out there in capacities as small as 64GB) is more likely to have some spare capability for put on leveling.
Evaluation: What comes subsequent for microSD?
To this point, Silicon Energy, Lexar, Sandisk, Teamgroup and PNY have all launched 1TB microSD, with Kingston and Samsung quietly remaining on the sidelines.
For many use circumstances, cloud storage, low cost bandwidth and ubiquitous high-speed connectivity have made high-capacity, high-performance native storage a factor of the previous. That is one purpose most high-end smartphones now not provide detachable storage.
So, will others observe Micron’s steps with larger-than-1TB microSD playing cards? Probably, however they gained’t come low cost in an ever-shrinking market.
One function that didn’t make it into the i400 is SD Specific, the high-speed expertise that would increase knowledge transfers to 4GBps. The issue is that it’s often a chicken-and-egg situation the place readers/suitable units should not available to justify a major enhance in the price of elements.
