I’m certain if you happen to confirmed a 4TB M.2 NVMe to the inventor of the primary ever pc storage drive, they’d be fairly shocked. Today these absurdly massive storage units are considerably regular for avid file hoarders, and much more absurdly massive HDDs are on the market. Yet as somebody who’s loads aware of trendy storage requirements, even I’m taken again by how Micron has squeezed 1.5TB of storage onto this microSD card the dimensions of my fingernail. There’s some wizardry occurring there.

This is Micron’s new 1.5TB i400 Industrial microSD, introduced at Embedded World 2022. It’s constructed to run all day, on daily basis for as much as 5 years. Though 1.5TB of storage is perhaps wolfed up lengthy earlier than then, in a month or 4, apparently. Still, it is meant to make life simpler for an always-on digicam, and it certain sounds up for the job.

Now that is not essentially the most thrilling use case for a excessive capability storage machine if you happen to’re a budding PC gamer, and it is perhaps slightly gradual to run video games slotted into your Steam Deck (at 30MB/s it isn’t the quickest round—although the hand-held does help as much as 2TB, as do many telephones), however there’s some fascinating tech at work behind the scenes right here to make this form of high-capacity SD attainable.

Micron is rolling out its 176-layer 3D NAND to ship that form of excessive capability in a compact space—the extra layers you’ve gotten, the extra bits you may match into an space and the reminiscence density shoots right up. This is a comparatively new know-how (introduced again in 2020) for the corporate, and it is solely not too long ago dropped into new SSDs within the kind components we want on PC on the tail-end of final yr (with the P5 Plus) and the start of this yr (with the P3 Plus).

Large jumps in NAND layers means larger drives in smaller chips,  and Micron’s subsequent step is 232-layer 3D NAND, marking one other main leap in reminiscence density. 

Storage know-how actually is advancing at a price of knots.
