Intel Will Double SSD Density By Summer 2011
Intel and Micron have been collaborating to shrink NAND circuity even more, doubling the density in their flash chips, they will reduce the cost of solid state drive storage. The same duo is responsible for a joint venture dubbed IM Flash Technologies (IMFT), the same company that released 25 nanometer circuitry in 2010. The company plans on releasing an enterprise-class SSD (not pictured) based on 20nm circuitry, running as a PCI Express expansion card. The new PCIe card, called the P320h, will be the successor to Micron’s first enterprise-class SSD, the P300, which was based on single-level cell (SLC) NAND flash memory.
The new card will use RAIN technology. RAIN is an acronym that stands for Redundant Array of Inexpensive Nodes, and is the close cousin to RAID technology. The “D” in the latter acronym simply refers to “disks.” RAIN incorporates the building blocks of a grid storage architecture that allows processors and disk storage to be placed in the same unit. For Micron, using RAIN technology will also mean making use of additional NAND as a cache to increase performance. IM Flash Technologies is working hard to overcome obstacles in nanotechnology, one of which is making the error detection code better to spot anomalies in the data. With such small technology, a human hair is 3,000 times thicker than 25nm, so every design requires much thought. The hard work doesn’t go without reward. The smaller circuitries will allow for much more affordable SSDs, one thing many of us have been waiting for.
