@Rick, no, I too have the 128GB model. The new Dell has a 'problem'. It came with a 1TB SATA 3 drive, but the darned system has only ONE SATA 3 port. This is where it got interesting. 'Who' should be on SATA 2? The boot drive or the data drive? Should I sacrifice a booting and OS file loading for data loading speed? I used ATTO Disk test on each drive on each port. Decided to put the OCZ on SATA 3. However, when running, other than the boot video display as things took a slightly longer time (I saw the flag complete for instance), the 'feel' of the system was about the same.
Spec's can be misleading too. Does it really matter between any as long as they use the same port and are built for the same SATA level?
@WHS, reading that post before I saw the next one I had the same question? Not only that, but there was a FLASH UPDATE for the Vertex 4 around the time I got mine. I wonder what level the poster was using, if it was in a SATA III port, and even if a SATA 3 cable was used? I bought a SATA 3 cable, blue in color and it appears it might be shielded? SATA III that came with the machine was orange/red, flat, and might not be shielded? Not sure if there is really a difference (didn't try switching and running benchmarks) in those cables though?
