Only about 1 second separates the 2TB MP600 from the top performing flash-based SSD on our chart, so we are not going to ding the MP600 for that. It is still plenty fast and if you factor in how much better it performs in our other tests, this result is rather insignificant.
PCMark 8 accurately represents real-world performance which is why we consider it the most important benchmark we run. This is typically where we find the largest performance disparity between 1TB and 2TB models.
For comparison, we included 1TB SSDs that have the same flash and controllers as those on our 2TB chart.
First let us compare the 1TB MP600 to the 2TB model. We find a difference of less than 10MB/s in storage bandwidth. The next one we can directly compare is Samsung's EVO Plus and we find that the 1TB version is 42.55 MB/s faster. The ADATA XPG SX8200 Pro 1TB and the HP EX950 2TB both use the same flash and controller, so they are comparable. The SX8200 Pro at 1TB is 47.08 MB/s faster than the 2TB EX950 Pro. Finally, the 1TB Corsair Force MP510 and the 2TB MDD BPX Pro both use the same flash and controller, so they are comparable as well. The MP510 1TB is 77.65 MB/s faster than the 2TB BPX Pro.
This is the data we refer to most when we state 1TB SSDs are almost always significantly faster than 2TB versions. Except for the MP600 and the 905P, the 2TB versions of the drives on our chart are between 7 percent and 13 percent slower than their 1TB siblings. By comparison, the MP600 is only a little over 1 percent slower at 2TB than 1TB.
