SandForce SF-1200 Features
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.
OCZ Vertex 2 Specifications
Based on a cutting-edge new architecture, Vertex 2 Solid State Drives raise the bar once again and deliver unprecedented performance for the complete gamut of gaming and professional multimedia applications. OCZ designed the Vertex 2 to surpass the competition where it counts most, pushing the limits in both sequential and random read/write rates. With spectacular performance in 4k file writes up to 50,000 IOPS, these latest drives take productivity to the next level with over ten times the performance of the previous generation. Using the latest controller technology, Vertex 2 not only provides a faster, more responsive PC experience, but promotes cooler, quieter, and more energy efficient conditions compared to traditional mechanical hard drives.
With sheer performance that outpaces the competition, the Vertex 2 doesn't lose sight of what makes an SSD the ideal storage alternative to hard drives and delivers the quality, reliability, and durability demanded by consumers that will not settle for anything but the best. Built with SATA 3Gb/s, the Vertex 2 Series easily integrates into today's mobile and desktop platforms and features TRIM support to optimize performance over the drive's lifespan as the ultimate Windows 7 notebook or desktop upgrade. OCZ Vertex 2 SSDs are available in 50GB to 480GB and come backed by a 3-year warranty and 2 million hour MTBF for ultimate peace of mind.

Comments
BTW. iometer is highly affected by compression - I have no troubles reaching ~45000 IOPS with my older Indilinx based SSD on a compressed NTFS partition.
Thomas
I will email you my Iometer configuration file, so that you may reproduce our test exactly as we conduct it. Please be informed that all SSDs are wiped clean using DISKPART "clean all" prior to testing. Also note that this is the total IOPS reported by the test, and not an individual read or write.
Do you think this is totally controller related?
BTW, sanity erase or a format of the whole drive (not a quick format) under win7 with a TRIM enabled AHCI driver+controller will restore the factory performance, not sure if a "diskpart clean all" will do the same.

Thank you for bringing this to our attention. These specification are pulled directly from the manufacturer-supplied data sheet, and are often subject to change without notice. I would consider the specifications listed on the website to be the most current and accurate.
