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 in both the read and write tests. The read figure of 7,252MB/s is 148MB shy of the official 7,400MB/s with the writes just 65MB/s shy of the official 6,500MB/s at 6,435MB/s.

128KB Sequential Read.

At QD1, the 2TB CRAS C925 just makes it into the top ten of the Sequential read results table. At QDs 2 and 4 it makes slight progress up the charts but at QD32 it drops to a mid-table position.

128KB Sequential Write.

When it came to the Sequential write test, the drive's worst performance compared to the drives around it 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 QD2.
