Why The SandForce Controller Is Special
SandForce isn’t an SSD manufacturer, but they manufacturer the controller, which is without a doubt the heart of an SSD. SandForce produces two controllers: the SF-1200 and SF-1500. The SF-1200 is the client controller, while the SF-1500 is designed for the enterprise market. Both of the SandForce controllers support MLC flash, but only the SF-1500 supports SLC for the enterprise market.
DuraClass technology represents a set of NAND flash management features that work in tandem to deliver world-class SSD reliability, performance, and power efficiency that differentiate SandForce SSD Processors from standard flash controllers. Of particular importance is the use of processing elements to optimally overcome a number of the inherent issues associated with commodity NAND flash memory.
DuraClass features like DuraWrite optimizes the number of program cycles to the flash effectively extending flash rated endurance by 20x or more when compared to standard controllers. This controller uses highly optimized wear leveling algorithms that help extend flash endurance. Advanced Read/Program Disturb Management is also taking place, which safeguards against errant re-programming of cells during read and program cycles.
The controller also has powerful flash media error correction (ECC) and RAISE (Redundant Array of Independent Silicon Elements), which deliver an orders-of-magnitude improvement in drive reliability versus today’s best enterprise HDDs and SSDs.
The result is single-drive RAID-like protection and recovery from a potentially catastrophic flash block failures – all while avoiding the inefficiencies of traditional RAID.
