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 drive showed smooth increases in performance as the queue depth deepened, without any noticeable drama. The Kioxia Exceria PRO G2's QD1 performance ranged from 23,647 IOPS (96.86MB/s) with a single thread up to 94,547 IOPS (313.79MB/s) using four threads.

At QD8, the single-threaded performance had risen to 159,341 IOPS (652.66MB/s), while the four-threaded performance ended at 499,274 IOPS (1,808MB/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 rate of acceleration then slowed, with the performance for all four threads beginning to plateau out.
