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 408K IOPS.
The full performance average of the Micron 9550 in 8K random write is 408K 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 QD16 which is a bit later than that Memblaze Pblaze 7, but it has the tradeoff of maintaining much higher IOPS from QD8…150K on average in fact.
The 9550 8K read performance of 1793K IOPS is very impressive. Once again, its performance curve leveled off ahead of the Kingston and Memblaze.
8K 70/30
8K 70/30 is representative of a typical database workload and just over 900K average IOPS is a powerhouse of a result.
8K 50/50
The Micron 9550 MAX 3-DWPD SSD surpassed the performance of the group as would be expected from this SSD. It maintained an average of 656K IOPS throughout QD 128-4096, and once again is the top result to date.
REPORT SUMMARY AND FINAL THOUGHTS
We started this report highlighting Micron’s assertion that the Micron 9550 is the fastest data center SSD available today… period. Well, they weren’t wrong. Not only did the 9550 MAX top each and every test we through at it (128K seq read and write, 4/8K read and write and 4/8K 50/50 and 70/30), but also, it walked all over its own listed specifications. This SSD is a powerhouse.
The Micron 9550 is capable of sequential read and write performance of 14.7GB/s read and 11.4GB/s write with up to 3.4 million IOPS but this really is not this SSDs strong points. The 8K 70/30 mixed workload has well over a 200K IOPS stretch on the next best, which just so happens to be the Micron 7600, and this is very similarly reflected in the 8K 50/50 and 4K mixed workloads as well. 4K 70/30 mixed load IOPS of 1300K plus is unheard of. Micron has done their homework in the design of this SSD and that has paid off with amazing performance. This SSD comes with a 5-year limited warranty and pricing is as one might expect for the best there is.
