We used CrystalDiskMark 8‘s custom settings to test the Sequential read and write performance of the drive through a range of queue depths. The setup for the tests is listed below.
128KB Sequential Read / Write.
Transfer Request Size: 128KB, Thread(s): 1, Outstanding I/O: 1-32.
With our 128KB Sequential tests, we came up just short of the maximum figures for the drive in both the read and write tests. The read figure of 7,155MB/s (QD16) is 245MB shy of the official 7,400MB/s, while the writes are just 149MB/s shy of the official 6,500MB/s, with a peak of 6,351MB/s (QD4).
128KB Sequential Read Performance v QD
At QD1, the 2TB CRAS C925G sits just outside the top ten of the Sequential read results table. At QDs 2 and 4, it makes progress up the charts, but at QD32 it drops to a lower mid-table position.
128KB Sequential Write Performance v QD
When it came to the Sequential write test, the drive's worst performance compared to the other drives was surprisingly at QD1. As the queue depth deepened, the performance improved, and the drive started to climb up the table with the best performance at QD4.
