AS-SSD Incompressible Sequential Performance

The AS-SSD sequential benchmark uses incompressible data for all of its transfers. The result is a pretty big reduction in sequential write speed on SandForce based controllers.

    doesn't the Z version let you access the CPU's video decoding/encoding engine while having an external GPU?
    While with the P and H versions you have to choose one or the other?

    In considerin an SSD for an OS X boot volume should one be more concerned with compressible data or incompressible data? I wondering because I know OS X compreses some of it's OS files and presumably many apps do the same thing. Further I'm assuming the light workload test uses a windows simulation, can anyone say if/how that would differ from OS X?

    I'm probably more worried about it than I need to be but trying to decide between OCZ/OWC, Intel and Crucial and still not clear which is best for a dual drive setup in a MacBook pro.

    "OCZ is still SandForce's favorite partner and thus it gets preferential treatment when it comes to firmware."

    I just confirmed with OWC, they're shipping the 6G with the 60K IOPS read/write frimware. Hope you update your article soon. This is kinda misleading, I'm reading comments here and people think that only OCZ drives have the 60K IOPS firmware.

    I had the Crucial C300, OCZ Vertex 3, and the OWC Extreme 6G in my laptop on a Sata6G connection... and honestly I didn't notice a difference in speed between the three of them. Against the Vertex 2 and the Intel X-25, there was a slight difference. In the end, I decided to go with OWC Extreme 6G for one reason... **** FIVE YEAR WARRANTY ****!!! That's friggin' awesome... ONLY SSD to offer a 5 year warranty on an SSD. And costwise, they're around the same or lower as the rest of the competition.
