Exascend PD5 Gen5 7.68TB Enterprise SSD Review – 15GB/s Throughput with 3000K+ IOPS and Exceptional Random Writes

8K RANDOM READ/WRITE

We precondition our enterprise SSDs using 100% random 8K writes at QD256  for two drive fills. Performance data is recorded every second.  We track this data to monitor the enterprise SSDs transition to steady-state and to verify that steady-state conditions are achieved before initiating queue depth testing.

Steady-state is established after a full drive fill and the average steady-state 8K random write performance is approximately 420K IOPS.

The PD5 8K read average performance of 1400K is decent.

8K 70/30

8K 70/30 is representative of a typical database workload and 640K IOPS is great.

8K 50/50

520K 8K 50/50 write IOPS is a decent result and contributes once again to placcig the PD5 unexpectedly ahead of other SSDs.
