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 463K IOPS.
The performance average of the Memblaze 7946 in 8K random write is 463K IOPS which is the best result we have had to date with any ‘uncompressed’ SSD.
The 7946 8K read average performance of 1730K is very impressive.
8K 70/30
8K 70/30 is representative of a typical database workload and 1013K IOPS from a 3-DWPD SSD is very impressive. This is the top result, once again, of any ‘uncompressed’ SSD to date.
8K 50/50
745K 8K 50/50 write IOPS is something only the MemBlaze 7946 achieved with respect to 3-DWPD enterprise SSDs
REPORT SUMMARY AND FINAL THOUGHTS
What can we say about the Memblaze 7946 Gen5 6.4TB E3.S Enterprise SSD that isn’t obvious? Given exception to the ScaleFlux CSD5320 with 2:1 compression, the Memblaze Pblaze7 7946 pulled off the absolute best results to date for both 4K and8K 50/50 and 70/30 mixed load operation, as well as one of the top marks for 4K random write IOPS. This was actually very surprising as the initial sequential read and write performance didn’t seem to project what this SSD could actually do.
The Memblaze 7946 just may be one of, if not the top SSDs we have tested to date. It is ideal for any 50/50 or 70/30 database application as well as cloud and hyper-scasle computing, deep learning and big data analytics, OLTP, high frequency trading,, ERP, SAP or HANA. Editor’s Choice!
