SF-1200 Client SSD Processors Overview
Performance and Power Optimization
Solid State Drives (SSDs) are being widely deployed in client computing platforms due to optimizations in durability, boot-up time, application performance and responsiveness, and power savings vs. Hard Disk Drives (HDDs). SandForce™ SF-1200 SSD Processors are revolutionary SoCs designed specifically to maximize these SSD benefits with enhanced enterpriseclass reliability, performance and security in costand power-sensitive mobile computing environments. The SF-1200 is a true single-chip SSD processor designed for volume manufacturing and its high integration enables up to 512GB densities on a 2.5” or 1.8” drive form factor. By eliminating the need for an external DRAM cache, power, cost and board space is minimized. It offers best-in-class, consistent performance for the entire life of the SSD made possible by highly innovative DuraClass™ technology.
SSDs are technically capable of outperforming traditional rotating hard disk drives, but the limitations of flash memory often require a conventional flash controller to limit the write speed to improve the endurance. The SF-1200 SSD Processors do not have this restriction. DuraClass technology enables the processor to maximize both the endurance and write performance for the life of the SSD fulfilling the promise of high speed flash memory. In extremely low-power environments, the SF-1200 can tune total SSD power consumption vs. performance by limiting the number of simultaneously active flash devices. It also supports an ultra-low power mode to maximize battery life.
Endurance and Longevity As each generation of Flash memory evolves and the silicon geometries shrink in order to dramatically lower $ /GB, the endurance of the individual cells on the die is dropping at a very high rate. Commodity MLC today supports 3-5K program/erase (P/E) cycles while the memory of tomorrow will likely support much less with the benefit of lower cost for broader SSD adoption. DuraWrite™ technology optimizes writes to the Flash memory over conventional controllers increasing the overall endurance and reliability of the SSD. Highly intelligent block management and wear leveling also extends the overall endurance. With this technology, SSD manufacturers can offer their high volume, mobile customers enterprise-class reliability and at least 5-year lifecycles.

Mobile Computing Security DuraClass technology automatically stores data in a highly secure, AES-128 encrypted format. This also prevents would-be thieves from extracting data directly from the flash memory should they ever have access to the drive. An optional disk-level password can be required prior to system boot adding an extra level of data security assurance for business travelers carrying confidential information.
Data Protection and Reliability The SF-1200 Mobile SSD Processors provide data protection that surpasses the leading high-performance enterprise HDDs used today. This comes from a combination of superior ECC algorithms with up to 24 bytes protection and the unique RAISE™ (Redundant Array of Independent Silicon Elements) technology. RAISE provides the protection and reliability of RAID on a single drive without the 2x write overhead of parity. This capability is transparent to the end-user and provides peace-of-mind for mobile SSD OEMs knowing their customer’s data is protected.
