Goodbye 176-layer NAND, Hi there 232-layer NAND
You would possibly suppose that the primary PCIe 5.0 drive could be the highest story as an alternative of the primary hyperlink under the fold, however there may be information that’s a minimum of as thrilling as that. Micron have simply introduced the small print on their new 232-layer NAND, which is quicker and extra energy environment friendly than their present 176-layer NAND, and can be utilized on any era of PCIe SSD.
Their information sheets declare the brand new 232-layer NAND can present as much as 2.4GB/s of bandwidth, or a few 50% soar over their present NAND. The brand new design incorporates NV-LPDDR4 for the cache which reduces the facility draw of one in all these new drives by 30% in comparison with Micron’s earlier era.
The 232-layer NAND additionally will increase the variety of planes from 4 to 6, and every of these planes have impartial learn functionality, which helps clarify the large enhance in bandwidth. It’s already in manufacturing and needs to be out there in Essential SSDs within the not too distant future. It will likely be fascinating to see this new NAND in each PCIe 4.0 and 5.0 drives.
