SandForce is a company that produces a number of different processors that control flash storage inside an SSD or computer. These controller chips can have a huge impact on how the computer performs overall including having a major impact on speed and battery life. The company has announced new controller chips promising significantly improved battery life called the SandForce SF-2200/2100 Client Flash Storage Processors.
Both of the new storage processor lines are aimed directly at the stringent power consumption requirements of ultrabooks. The most important new feature of the storage processors is that they consume significantly less power than predecessors promising as much as an extra hour of runtime per battery charge. An extra hour of runtime is a huge improvement in consumption.
SandForce is talking about three new specific products aimed at the ultrabook market, including the LSI SandForce SF-2141, SF-2241 and SF-2281 client FSPs. These processors have other benefits for the ultrabook market than extending battery life. The new processors will enable system boo and wake times to be reduced and are designed to meet the low C-height product requirement in the ultrabook market.
The controllers support SATA 6Gb/s host connectivity and are able to address between 24 GB and 512 GB of NAND flash memory. SandForce says that the processors support virtually all MLC flash product families. I'd wager these new flash controllers would find their way into other products as well since ultrabooks aren't the only computing products that could benefit from an extra hour of battery life.
