Planning to buy an SSD, stop and think again? Well, with the need of speedy access to memory, SSDs have been developed for users which are popular in the market now-a-days. But the biggest drawback of them is low space and their cost. For instance, a 256 GB SSD will cost around $120. So, for your amazement there won’t be any compromization of memory capacity for speed anymore. Say goodbye to all those rotating disk memory drives, as Toshiba and Intel partnered with Micron have developed a way to fit in a 10TB storage capacity under the hood, thanks to 3D-Nand technology.
What is 3D NAND memory?
Usually in an SSD there is single layer wayfarer which is 40-50nm thick which is used to store data on it.
Stacking cells is done vertically one above another to form a 3-Dimensional wayfarer. This stacking of cells (usually 10-15nm thick) provides a higher capacity or volume ratio in a comparatively smaller physical space. It also drastically improves electrical efficiency by shortening the length of the interconnection between the cells, which reduces the power consumption a lot which is then flashed as a form factor for storage. The read and write speeds are generally around 1GBit/s.
This is expected that the future SSDs and flash devices using 3D NAND technology will be cheaper. Recently, Toshiba and Intel-Micron revealed a new class of 3D NAND memory-chips. Toshiba announced recently that it has successfully created the first 48-layer NAND in the world. This leading Innovation company, Toshiba, had invented the flash memory that has the smallest NAND cell of 15nm in the world.
Meanwhile, Intel-Micron revealed that they are fabricating their own 3D NAND memory units having 32-layer of NAND chips that will be arriving in the SSDs within a year. The processor beast company, Intel is currently sampling even larger capacity NAND memory with 32GB chips. Micron said the chips will be available in 2 versions:
1.) M.2 PCIe SSDs whose capacity will be up to 3.5TB 2.5-inch SSDs with 10TB of capacity — on par with the
2.) 2.5-inch SSD with storage capacity of 10TB.
So, soon Intel and Toshiba will be giving a neck-on-neck competition to each other. Contrary, the result will be in the favor of consumers, as you fellas will be blessed with high storage capacity in low cost. With this 3D NAND technology, SSDs — the spinning hard disks (HDDs) will be obsolete soon enough.
