New SSDs revealed in leaked Intel roadmap

Intel has certainly been busy on the SSD front. The company released 510 and 320 Series solid-state drives in recent months, and more fresh offerings are on the way according to a leaked roadmap posted by Engadget. Several new models are revealed, including a new family of enterprise-grade SSDs that will replace the old X25-E.

The roadmap shows two members of this upcoming 700 series: a 710 SSD code-named Lyndonville and a 720 model dubbed Ramsdale. The former grafts 25-nano MLC memory to a 3Gbps SATA interface, while the latter combines 34-nm SLC memory with a "PCIe 6Gbps" interface. There's no such thing as 6Gbps PCI Express, but I wouldn't be surprised to see Intel use a PCIe 2.0 interface on its next-gen enterprise SSD.

In the fourth quarter of this year, consumers can look forward to new members of the 500 and 300 series. A Paint Creek SSD limited to 40 and 80GB capacities is slated to replace the old X25-V, while a 520 model named Cherryville looks poised to supplant the existing 510 Series. Both drives will use 25-nano flash, but it's unclear whether Cherryville will retain the Marvell controller used in the 510 Series. The 520 is listed with a 6Gbps SATA interface, at least.

Perhaps the most unusual entry in the roadmap is Larsen Creek, a 300-series SSD with a 3Gbps interface and just 20GB of 34-nano SLC NAND. Larsen Creek is listed as a "caching product," hinting that Intel might be working on something similar to Marvell's HyperDuo SSD caching scheme. Indeed, a leaked ASRock release suggests upcoming Z68 chipsets will feature an SSD caching scheme called Intel Smart Rsponse Technology.
