Client SSD Processors

Overview

SandForce SF-1200 SSD Processors enable commodity flash memory to reliably operate in cost and power sensitive client computing environments. The SF-1200 is a true single-chip SSD Processor designed for volume manufacturing and outstanding performance. Innovative DuraClass™ technology delivers world class reliability, endurance, performance and power consumption.

Endurance and Longevity

As each generation of flash memory evolves and the silicon geometries shrink - performance, reliability, endurance, and data retention are negatively impacted. DuraWrite technology extends the life of the SSD over conventional controllers, by optimizing writes to the flash memory and delivering a write amplification below 1, without complex DRAM caching requirements.

Performance and Power Optimization

SSDs are capable of significantly outperforming traditional HDDs, but typical controllers haven’t delivered the compelling value necessary for mainstream adoption. SandForce DuraClass technology enables the SSD to maximize both the endurance and performance for the life of the drive fulfilling the promise of high speed flash memory in client computing applications and improving system performance by up to 50% as measured by the SYSmark™ Benchmark.

Mobile Computing Security

The SF-1200 has built in AES-128 bit encryption controllable by a configurable user password. This feature prevents would-be thieves from extracting data directly from the flash memory should they ever have access to the drive.

Data Protection and Reliability

SF-1200 SSD Processors provide up to 100x greater data protection than today's SSDs, and leading enterprise HDDs. This is a result of superior ECC protection and unique RAISE™ (Redundant Array of Independent Silicon Elements) technology. RAISE provides the protection and reliability of RAID on a single drive without the significant write overhead.
