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 Reads

In the QD1-QD8 random read tests the CRAS C910 produced smooth increases in performance as the queue depth deepened without any noticeable dramas. At QD1 the drive speed ranges from 18,102 IOPS (74.14MB/s) using a single thread up to 71,941 IOPS (294.67MB/s) using four threads. At the end of the test run at QD8, the single-threaded performance had risen to 123,031 IOPS (503.93MB/s) while the four-threaded performance rose to 364,715 IOPS (1,403.87MB/s).

Random Writes

In the 4K write tests, the performance rose quickly from QD1 to QD2 for all four tested threads with the fastest rise seen in the three and four-threaded tests. The single and two thread performance plateaued out after QD2 while the other two threaded tests saw the performance start to level off at QD4.
