LSI Corporation has announced enhanced power consumption features for its SandForce SF-2200/2100 Client Flash Storage Processors (FSPs) geared for ultrabook applications. These FSPs support SATA 6Gb/s connectivity from 24-512GB of NAND flash memory.
LSI Corporation has announced enhanced power consumption features for its SandForce SF-2200/2100 Client Flash Storage Processors (FSPs) geared for ultrabook applications. These FSPs support SATA 6Gb/s connectivity from 24-512GB of NAND flash memory.
The SandForce SF-2200/2100 is part of LSI’s second generation of SandForce SSD Processors, featuring a DRAM-less single chip solution. SandForce SF-2200/2100 FSBs are designed for configurations of up to 512GB in 2.5” or 1.8” drive form factors as well as ultra small form factors. LSI’s announcement cites TechSchi Research’s “Global Ultrathin Portables Market Forecast & Opportunities” (2017), forecasting a 92 percent compound growth rate in the ultrabook market through 2017. New LSI SandForce power management optimizations are intended to enable SSD manufacturers to develop drives that extend battery life and reduce system boot and wake times, important considerations for ultrabook platforms.
LSI SandForce SF-2141, SF-2241 and SF-2281 client FSPs have received power management optimizations. In low-power environments, the these FSPs can limit the number of simultaneously-active flash devices. It also supports an ultra-low power sleep mode to maximize battery life. According to LSI’s MobileMark07 Battery Life benchmarks, these improvements provide as much as one hour longer battery life.
