Note: Crystal Disk Mark 3.0 is not available to the public yet, but the Technical Preview does allow us to test 4K performance at queue depths of 4 and 32 in addition to 1. The current release Crystal Disk Mark only shows us QD 1.
In CDM we are looking at the 4K and queue depth performance. The Lenovo drive shows near 20MB/s 4K performance which is very good for a low cost SSD, but we see that the Toshiba OEM drive does not support NCQ and 20MB/s seems to be the ceiling.
Once again we see that the write operations are where the drive has issues. When you look at the numbers we see that the Lenovo drive resembles the 4K performance of the WD VelociRaptor more than it does the SSDs.
That concludes our synthetic benchmarks. Let's take a look at the real world tests and see if what we learned from the synthetics carries over to the real world.
