SandForce SF-1500 Performance

OCZ Vertex-2 Pro Enterprise SSD

The OCZ Vertex 2 Series is the industry-leading flash-based storage solution, delivering the performance and reliability of SSDs with superior performance across a wider spectrum of consumer and enterprise class applications. The OCZ Vertex 2 Series is the result of all the latest breakthroughs in SSD technology, including the first model on the market to use the SandForce controller.

All Vertex Series 2 SSDs come backed a leading three year warranty and OCZ's legendary service and support, giving you added peace of mind for your high performance investment. Additionally, enthusiasts are put at the forefront of cutting edge technology with the available firmware updates and active online SSD community.

Perfect for notebooks and desktops alike, the Vertex 2 Series is ideal for energy-efficient mobile computing to extend battery life, increase the speed of access time, and provide a durable alternative to conventional hard disc drives with superior shock resistance. High capacities and low power consuming NAND flash technology provide the necessary performance and battery life boosts generated by the proliferation of mobile gaming and new ultrathin laptops.

The OCZ Vertex 2 drives feature a durable yet lightweight alloy housing, and because OCZ SSDs have no moving parts, the drives are more rugged than traditional hard drives. Designed for ultimate reliability, Vertex Series SSDs have an excellent 1.5 million hour mean time before failure (MTBF) ensuring reliability over the long term.

Have to say that standard SSD/HDD tests can not correctly test SandForce-based SSDs.

The main reason is in the nature of the SandForce chip - it is not only RAID 5 - like controller, it is also a data compression engine.

So, any testing data stream (ually a small repeated data pattern) dous not test a drive, but only a compression engine productivity.
This results in very high throughput and IOPS.

To test the drive itself, the data stream should be virtually uncompressible - think this will give quite another results.

Also, database read pattern (reading random parts af a huge file) will not be that fast even on highly compessible data.

So, the good test of this drive should provide benchmarks on both - highly comressible and virtually uncomressible data, giving the possible productivity range in the real live.

You are just wrong lol,

mabye the benchmarks are misleading however you need to consider the way these controllers work, indilinx has a huge write amplification (x10) where as SANDFORCE have a write amplification of x1.1 meaning the MLC NAND on a SANFORCE controller will last much longer than any indilinx controlled SSD. I own both indilinx and sandforce based SSD's and sandforce performance is much better. Have a read on the sandforce website, they have a fact and fiction section, its very interesting!

Once again - I do not say SandForce is worse or better than other controllers - it's just a bird of another flock and should be treated (tested) accordingly.

On highly compressible data it will by definition outperform any other drive, but in other applications it might lag way behind, and the tests show nothing on this side. We may only guess what is a compression impact on the internal drive productivity.
