Micron has introduced the industry’s largest storage capacity microSD card. It will be marketed under i400 series in capacities of 64 GB, 128 GB, 256 GB, 512 GB and 1 TB. The great novelty is a version with 1.5TBsegment record.
Although many smartphones no longer support them (thanks to Apple’s bad-copy that almost all other manufacturers reproduce), microSD cards are still a essential product group to increase the storage capacity (or run software) of hundreds of millions of devices, from smartphones to cameras, through drones, tablets, GPS, portable consoles and much more.
The Micron i400 uses 176-layer 3D NAND memory from the company and, due to its high density, is ideal for small form factor solutions such as microSD. They are rated for 24/7 operation, with a mean time between failures of two million hours and a performance guarantee of at least five years. They can work in environments between -25 and 85 degrees Celsius, and are protected against damage from water, magnets, X-rays, impact and shock.
In terms of performance, the minimum supported write speed (sequential) will be at least 30 MBps, while random reads/writes are rated A2 quadrupling the minimum random reads/writes (4,000/2,000 IOPS) of the original version .
Certainly, there are faster microSD cards, but the storage capacity of the new Micron cards is their best letter of introduction, since until now the limit was set at 1 Tbyte.
The company focuses its new cards on any market segment, professional, consumer or industrialespecially to store content from surveillance camera recordings or others for which up to four months of video sequences are cited.
1.5 Tbytes… that’s nothing for a format as small as microSD. Of course, the deployment of the new SD Express is underway, a level unknown until now for removable storage, since in addition to offering data transfers of up to 4,000 Mbytes per second they can reach a capacity of 128 Tbytes.
