SandForce SF-2200 Features
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-2200 series has built in AES-256 bit double 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-2200 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.

Comments
Sandforce webpages claim it is an option, but I am not aware of any currently available Sandforce based SSD that actually supports it.
The drive webpage (##edgetechcorp.com/) makes no mention of TCG Opal.
ATA password != TCG Opal
Full Disclosure: The product sample used in this article has been provided by EDGE Tech.
But thanks for including it.
