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.
In our read/write 70/30 mixed tests the SN580 produces a best result of 417,637 IOPS (1,170.64MB/s) using four threads and 149,826 IOPS (613.688MB/s) using a single thread.
