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 282K IOPS.
The full performance average of the Kingston DC3000ME in 8K random write is 282K IOPS which we expected to be half of that of 4k as it is moving twice the amount of data, but this performance curve is very impressive. It levels off at QD32 which is a bit later than that Memblaze Pblaze 7, but it has the tradeoff of maintaining higher IOPS from QD16.
The DC3000ME read performance of 1731K is very impressive and just a bit higher than the Pblaze 7, but once again, we had to take a very close look to ensure that Pblaze7 latency result was behind that of the DC3000ME.
8K 70/30
8K 70/30 is representative of a typical database workload and 665K IOPS from a 1-DWPD SSD is one amazing result and 125K IOPS better than the Memblaze.
8K 50/50
Once again, 465K 8K 50/50 write IOPS is something only a few enterprise 1-DWPD SSDs might achieve. Both drives did very well.
REPORT SUMMARY AND FINAL THOUGHTS
We didn’t start this report with any intention whatsoever of initiating a competition but we had to be impressed how the Kingston DC3000ME and the Memblaze PBlaze7 exchanged blows throughout. To the Memblaze Pblaze7 credit, it bettered in 128k read and write throughput, along with 4K read and write IOPS where the 4K write IOPS leveled off way before the Kingston at QD4 vice QD128. Having said that, the Kingston DC3000ME owned the course with respect to 70/30 and 50/50 mixed load testing along with 8K read and write IOPS. This is why it is so important to understand your specific compute need.
If you remember back to our Memblaze report, we spoke of how Memblaze is a Chinese company and we were very impressed that they had marketed different versions for different parts of the world. In Canada, we reviewed the 7A40, however the US receives athe 7940 with different US-centric components. We have a 7940 on the way btw. Getting back to Kingston, they probably have one of the largest customer base’s worldwide and they easily have the upper hand with respect to mass availability of the CD3000ME. Add to that their 5-year limited warranty and the fact that they have a reputation of having one of the best customer support systems in the business and this SSD is a sure-fire success.
