Sequential Reads and Writes
In HD Tune Pro we found a solid 100MB/s of sequential read performance over the best 2.5" SATA SSDs in this test under the same conditions.
The same can be said with the sequential writes. The performance in a clean state is impressive, but it only gets better from here.
After a realistic amount of 4K writes, we ran HD Tach to see where the write performance fell into place. We saw a drop in write performance, but not as bad as we see with many of the newer SATA III products on the market with 20nm flash.
Moving down the list we were surprised to see the 4K reads under 40MB/s. Given the direct to CPU interface, we just expected a little more, but this isn't our first PCIe NGFF SSD to run this test.
At the 2013 Samsung Global SSD Summit the Samsung beta didn't surpass 40 MB/s in 4K reads in this same test.
