Kioxia Exceria Plus G3 2TB SSD Review

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 random read QD1-QD8 tests the drive displayed smooth increases in performance through all the used threads and tested queue depths. At QD1 the drive speed ranges from 14,401 IOPS (58.98MB/s) using a single thread up to 56,997 IOPS (233.46MB/s) using four threads. At the end of the test at QD 8, the single-thread performance had increased to 104,891 IOPS (429.63MB/s) while the four-threaded test reached 285,286 IOPS (1,086.53MB/s).

Random Write

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. All four threads see the rate of increase in performance start slowing from QD2 onwards up to the end of the test run at QD8 in a consistent fashion. QD1 performance ranges from 85,211 IOPS (349MB/s) using a single thread up to 285,047 IOPS (1,167MB/s) using four threads.
