Micron Starts Producing Cutting-Edge 232–Layer NAND

Recently, Micron announced the production of their 232-layer TLC NAND. This new NAND will find itself in newer and faster SSDs. 

The new NAND has increases of 100% more write bandwidth, 75% higher read bandwidth, 50% faster transfer rate and a 28% size reduction.

Micron’s new NAND technology enables NV-LPDDR4, which is a low-voltage interface allowing for faster data transfers while not consuming much power. This can be helpful for mobile devices looking to offer fast performance. 

The 232-layer NAND has the highest ever TLC per square millimeter ever produced (at 14.6 Gb/mm2)3. “Micron’s 232-layer NAND is a watershed moment for storage innovation as first proof of the capability to scale 3D NAND to more than 200 layers in production,” stated Scott DeBoer. 

As for the availability, Micron’s 232-layer NAND is in production at its Singapore fab. It will initially featured on the company’s Crucial SSDs

For reference purposes, a 2TB chip package from Micron is a whopping 3x smaller than a US stamp allowing for more sleek and thinner designs for handhelds. If you decide to buy such an SSD, you can essentially watch around ~340 hours of 4K videos.

Samsung currently uses the 128 layer NAND, whereas SK Hynix boasts an impressive 176 layers. This goes to show that Micron is possibly years ahead of the competition. 

What does this mean for all of us?“, well to put it simply this new technology will allow for more storage to be produced at a rather cheap cost. It will be available to the general public in 1-2 years though, because newer technology takes time to be tested and improved so that no issues arise. Soon, we will see SSDs coming up in 8TB and higher flavors, although price may be a question mark.

Many speculate that the pricing for SSDs will remain the same, however, the actual storage capacity will increase dramatically in the years to come. 

Hard drives will not wither away with the launch of these new 232-layer NAND SSDs. Essentially, this is just a storage improvement done via stacking. Hard drives offer other conveniences such as not costing a fortune because a 100TB SSD is around $40,000. The WD Gold 20 TB Hard Drive is around $679.99 which when multiplied by five is just $3,399. So yes, SSDs are faster but they will not replace hard drives, not anytime soon
