Note: In this test we use the Lenovo W530 Mobile Workstation and a SuperSSpeed S301 SLC 128GB SSD to move a 15GB block of data to and from the target drive. This is part of our real world test regiment. Roughly 45GB of data resides on the target drive before the '15GB Block' is transfer. The 15GB Block is the same data we built for the Data on Disk Testing and is a mix of compressible and incompressible data.
Earlier in the review, I said we would expand on file transfers a little more. As you can see on the chart none of the drives make it past 310MB/s reading or writing data. This is a limit imposed by the Windows file system for the most part. Granted, you can get higher results with RAID arrays, but for everything over 300, you have to give a little back to Windows, the processor, the chipset and so on.
What this means for you is Vector's QD1 limit of 350MB/s and 840 Pro's maximum performance with the file system of 460ish MB/s still gives you around 300MB/s when transferring data. I know right, sometimes life just isn't fair.
