Email Server






The Email Server workload is a demanding 8k test with a 50/50 read/write distribution. This application is indicative of performance in heavy random write workloads.


The FlashMAX II and P420m are in a dead heat at 256 OIO, with an average of 93,771 and 92,416 IOPS, respectively. The FlashMAX II does tend to scale better at the lower 8 - 32 OIO. The P320h averages 166,028 IOPS.







File Server






The File Server workload tests a wide variety of different file sizes simultaneously with an 80% read and 20% write distribution. The wide variety of simultaneous file size requests is very taxing on storage subsystems.


The HGST FlashMAX II experiences significant variability in this test and averages 91,820 IOPS at 256 OIO. The P420m also has difficulty with variability during this test and averages 70,574 IOPS. The P320h averages 157,040.




Both MLC competitors experience significant variability in this strenuous test.




The FlashMAX II wins the test for MLC drives with 80,000 IOPS at 1ms, compared to 42,000 from the P420m. The P320h is off in a category of its own as it muscles its way through the workload.
