RANDOM PERFORMANCE BENCHMARKS
4K RANDOM WRITE/READ
We precondition our enterprise SSDs with 100% random 4K writes at a queue depth of 256 for two full drive fills. Performance metrics are captured every second throughout the process. This data allows us to monitor the SSDs’ transition to steady-state and confirm that steady-state conditions are reached before beginning queue depth testing. Steady-state is typically achieved after one full drive fill, and average 4K random write performance stabilized at around 1000K IOPS.
Listed specification for the Phison Pascari X200Z Gen 5 SSD is 950K IOPS for sustained random write 4K IOPS during steady-state operation and both capacities of the X200Z exceeded that spec with returns of 1000K, one of the highest 4K write average results we have seen to date.
Listed specifications for both Phison Pascari X2000Z Gen 5 SSDs is 3100K IOPS for sustained random read 4K IOPS during steady-state operation and both maintained 3100K through QD512 to QD4096.
4K 70/30
We never expected such but the 800GB capacity of the Phison Pascari X200Z made a commanding leap of the 1.6TB capacity in 4K 70/30 mixed loading testing, a 500K leap in fact to average an unheard of 2250 IOPS. This is the top result we have received to date for this specific test.
4K 50/50
Once again, both Pascari X200Z Gen5 SSDs pulled off some amazing 4K 50/50 mixed load testing results, the 800GB version remaining slightly ahead with an average of 2GB/s while the 1.6TB version levelled off at 1.7GB/s. These are the highest results we have ever received in testing.
