Intel confirms 25-nm NAND for Cherryville, Hawley Creek SSDs


— 5:33 PM on September 15, 2011

IDF — With Intel's 320 Series solid-state drives already using 25-nm NAND, and the freshly announced 710 Series sporting high-endurance versions of those chips, Intel is keen to move its other SSDs to 25-nm flash memory. The 510 Series, which currently uses 34-nm flash tied to a Marvell controller, appears destined to be supplanted by a "2nd generation SATA III" SSD code-named Cherryville. It's unclear whether Cherryville will replace the 510 Series entirely, and Intel hasn't officially named the controller that will reside under the hood. We can, however, confirm that the drive will be packed with 25-nm MLC NAND. Looks like it'll be faster, too.

34-nm flash can also be found in the 311 Series SSD Intel introduced for the Smart Response caching tech that accompanies Z68 motherboards. Intel equips that drive with pricier SLC memory due to the high volume of writes associated with its caching mission. Those SLC chips are making the transition to 25-nm production for a next-gen caching SSD dubbed Hawley Creek. The new chips should be cheaper to produce than their 34-nm predecessors, which could allow Intel to expand on the 311 Series' relatively modest 20GB capacity or lower its onerous $115 asking price.

Unfortunately, Intel is intent on keeping additional details on these new drives close to its chest. I'm terribly curious about Cherryville, and we'll be able to tell you more about the drive some time this fall.
