We used CrystalDiskMark 8’s custom settings to test the 4K 70/30 mixed read/write performance of the drive through a range of queue depths using a single thread and four threads.

4K Random Read Performance QD1-QD8

In the QD1-QD8 random read tests, the CRAS C925G exhibited smooth increases in performance as the queue depth increased without any noticeable issues. At QD1, the drive speed ranges from 17,990 IOPS (73.68 MB/s) using a single thread to 80,624 IOPS (330.23 MB/s) using four threads. At the end of the test run at QD8, the single-threaded performance had risen to 153,904 IOPS (630.39MB/s) while the four-threaded performance rose to 472,266 IOPS (1,934.4MB/s).

4K Random Write Performance QD1-QD8

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
