CHIPMAKER Intel has started shipping its 335 series solid state disk (SSD) drives, the first to use its 20nm NAND flash memory.

Intel's SSDs have a very good reputation for reliability and the firm has in recent years been cautious in incorporating technologies employed by its rivals. However now it has updated its mainstream SSD range and has started shipping the 335 series SSD drives boasting 20nm NAND flash chips using a High-K metal gate stack.

Aside from sporting Intel's leading edge NAND flash chips, the 335 series SSDs have 240GB capacity and deliver sequential read and write bandwidth of 500MB/s and 450MB/s, respectively. The firm also claims the drives have random read and write performance of 42,000 IOPS and 52,000 IOPS, respectively, and offers a three year warranty on the drives.

Rob Crooke, VP and GM Intel's of Non-Volatile Memory (NVM) Solutions Group said, "The Intel SSD 335 uses Hi-K/metal gate planar cell technology, which overcomes NAND process scaling constraints to deliver the smallest-area NAND cell and die in the industry. By pushing technology constraints and using process innovation, Intel can continue to progress SSD technology and pass along savings to our customers."

Intel's 335 series SSD drives come in 2.5in units but only in a package with a height of 9.5mm, meaning that those looking to upgrade their laptops will have to be able to accept the 'taller' SSDs. The firm is likely to roll out its 20nm NAND flash chips to its lower volume enthusiast range of SSDs soon, though it might be a while before the new chips will get certified for its high-end enterprise products. µ
