Today’s award-winning SandForce Driven™ SSDs are well known for their performance and features. The SandForce® SF-2200/2100 - the second generation of SandForce SSD Processors - continue accelerating SSD deployment in enthusiast and mainstream client computing platforms. The SF-2200/2100 is an ideal solution for portable storage applications where power consumption, boot-up time, application performance, responsiveness, and small form factor are important. The Client SSD Processors have integrated enhanced DuraClass™ Technology that is architected to leverage today’s densest SLC and MLC NAND flash memory. They deliver best-in-class performance, endurance, security, and power efficiency in a “DRAM-less”, single chip solution. Configurations up to 512GB densities in standard 2.5” or 1.8” drive form factors, as well as ultra small form factors (e.g. MO-297A, mSATA), are all possible.
Endurance and Longevity
As the geometries of each generation of flash memory evolves and shrink in order to dramatically lower $/GB, the overall flash endurance is dropping at a very high rate. The 2x/3xnm NAND flash memory has less than 5K P/E cycles. The memory of tomorrow will likely be even lower than that. DuraWrite™ technology optimizes writes to the flash memory over conventional controllers increasing the overall endurance and reliability of the complete SSD. Highly intelligent block management and wear leveling also extends the overall endurance. With this technology, SSD manufacturers can offer their high volume, client customers enterpriseclass reliability and at least 5-year lifecycles.
Performance and Power Optimization
SSDs greatly outperform traditional HDDs, and in many cases reach the limits of the bus interface. Advanced high speed SATA interfaces have been implemented in newer systems to remove this performance bottleneck. SSDs are perfect to take advantage of that higher speed interface. SandForce SSD Processors deliver performance that maximizes the throughput of a 6Gb/s SATA interface with balanced read/write speeds. In extremely low-power environments, the SF-2200/2100 can tune total SSD power consumption vs. performance by limiting the number of simultaneously active flash devices. It also supports an ultra-low power sleep mode to maximize battery life.
Client Computing Security
Data security is becoming a critical component in the digital age. SandForce SF-2200/2100 SSD Processors feature high-level security protocols to protect the security of data stored in flash memory. DuraClass technology automatically stores data in a highly secure AES-256 & 128 hardware encrypted format that double encrypts the data. The SF-2200/2100 SSD Processors also optionally support TCG OPAL security requirements. 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-2200/2100 SSD Processors provide data protection that surpasses the leading high-performance enterprise HDDs used today. This comes from a combination of a superior higher-level BCH ECC algorithm with up to 55 bits/512 Byte sector 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.
