However, it's worth bearing in mind that, right now, it's only the Sandy Bridge platform that's able to take advantage of the Vertex 3’s ludicrously quick headline speeds. Marvell's 91xx SATA 6Gbps controller chips that are used to provide SATA 6Gbps ports on X58 and P55 motherboards will almost always be connected via a single PCI-E 2.0 lane, which theoretically peaks at 500MB/sec, but realistically only delivers 400MB/sec. It’s a case of products moving faster than the platform, and that means than only owners of native SATA 6Gbps systems will get the full performance of the drive.

We tested AMD's SATA 6Gbps ports back when we looked at SATA 6Gbps port performance and found that they weren't as fast as marvell. We might take another look at SATA 6Gbps elsewhere when these drives are actually released. For now this is just a preview and we found SandyBridge to be plenty fast enough.
The speeds from the AMD boards (graphed in green) werenâ€™t brilliant in the 4KB test, largely matching the speed of the Intel ICH10R Southbridge (or its P55 or H55 equivalent), while the add-on SATA 6Gbps chips were mostly faster.
However, in the 1MB and 4MB tests, the SB850 (green in the graphs) held its own against the Marvell-powered ports. The Asus Crosshair IV Formula managed a read speed of 334MB/sec in the 1MB test, which is the third highest speed we saw
The slowest SB850 board in the 1MB test was the Gigabyte GA-880GMA-UD2H, a cheap £75 micro-ATX board, which was only 13MB/sec slower than the premium Asus RoG board. AMDâ€™s SB850 Southbridge is capable of fairly fast SATA 6Gbps speeds, so itâ€™s no surprise that few manufacturers have opted to use add-on chips on their AMD motherboards
