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.
Using a single thread the 2TB Kioxia Exceria Plus G3 produced results that ranged from 19,197 IOPS (78.63MB/s) at QD1 up to 174,526 IOPS (714.86MB/s) at QD32 where the performance starts to plateau off. Switching to four threads the performance rises from 74,865 IOPS (306.64MB/s) at QD1 up to 488,507 IOPS (2,000MB/s) at QD32 with no sign of levelling out.
