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.

# SF1500 ? and others tests ;)Federico La Morgia 2010-06-03 22:49
I saw on the website that there is a version of sandforce SF1500 enterprice class, you know if any SSD on the market uses to be able to test since SF1200/1220?

A tip, there is some PCI-Express RAID controller that supports RAID SSD without disable the TRIM command and other commands that provides the sandforce and has at least 8 channels like normal RAID controllers from 300-1000 euros?
Because it would be interesting to test 8-10 SSD with RAID controllers with Sandforce 0-1-5-10-50-60-51-61 doing many tests including those that completely filled and completely empty the resulting volume in order to understand how deteriorate the overall performance over time!

I understand that now I hate the fact that I beg you to do many more tests, some seemingly strange, but I think it could bring to light strengths and weaknesses nasconti that would not normally go out :)

So the manufacturers are marketing SSD's with known bugs and flaws in the firmware (1222), and it's up to the buyer to upgrade the firmware to get the SSD to work properly, OR IT DIES???

This has a bad smell!
