View Full Version : New OCZ Pro SSD... Bests Intel with interesting new tech

Jan 2, 2010, 12:17 PM
A very interesting new SSD from OCZ with incredible performance using the new SandForce controller with Durawrite technology that offers write amplification of only 0.5x?!?!

SandForce states that a full install of Windows 7 + Office 2007 results in 25GB of writes to the host, yet only 11GB of writes are passed on to the drive. In other words, 25GBs of files are written and available on the SSD, but only 11GB of flash is actually occupied. Clearly itís not bit-for-bit data storage.

What SF appears to be doing is some form of real-time compression on data sent to the drive. SandForce told me that itís not strictly compression but a combination of several techniques that are chosen on the fly depending on the workload.

Anand's conclusion...

The OCZ Vertex 2 Pro is the fastest single-controller MLC SSD Iíve ever tested, and itís not even running final firmware. Itís quite telling that SandForce decided to make its first public showing with OCZ. Perhaps all of the initial hard work with Indilinx in the Vertex days paid off.

The controller and product both look very good. The only concern for the majority of users seems to be price. For the enterprise market I doubt itíll be much of an issue. The Vertex 2 Pro should come in cheaper than Intelís X25-E in a cost per GB sense, but for high end desktop and notebook users it may be a tough pill to swallow. Especially for a controller whose reliability will only be proven over time. Iím curious to see what the cheaper SF-1200 based SSDs will perform like. Iím hearing that they offer the same sequential read/write speed, but have lower random write performance.

Saw the article - with any luck, this will lead to a price war and drastically more affordable high performance SSDs all around.

Thanks for the link. It's certainly interesting, and will help push some of the prices down.

I'll wait for them to release in the wild for awhile though, as I'm interested in the reliability, which is as of yet, totally untested (real use over time is needed).
