We used CrystalDiskMark 8 to test the random performance of the drive at lower queue depths (QD1 – QD8, where most of the everyday workloads occur) using 1 to 4 threads.

Random Read

In the QD1-QD8 random read tests, the CRAS C930 produced smooth increases in performance as the queue depth deepened without any noticeable dramas. At QD1, the drive speed ranges from 15,881 IOPS (65.05MB/s) using a single thread up to 63,353 IOPS (259.49MB/s) using four threads. At the end of the test run at QD8, the single-threaded performance had risen to 117,031 IOPS (479.35MB/s) while the four-threaded performance rose to 361,579 IOPS (1,481.03MB/s).

Random Write

In the random write test, the single and two-threaded performance plateaued out after QD2, while the other two threaded tests saw the performance start to level off at QD4.
