8K Random Read/Write
8K random read and write speed is a metric that is not tested for consumer use, but for enterprise environments this is an important aspect of performance. With several different workloads relying heavily upon 8K performance, we include this as a standard with each evaluation. Many of our Server Emulations below will also test 8K performance with various mixed read/write workloads.
The Seagate 600 Pro falls into the midrange between the superb read performance of the SM843 and the CloudSpeed 500. The Seagate 600 Pro averages 34,467 IOPS at QD256.
The Seagate 600 Pro and the CloudSpeed 500 trade blows in the 8K random write testing, with very close average speeds and similar write distribution. The Seagate Pro 600 comes in just below the CloudSpeed 500 with an average of 16,053 IOPS at QD 256.
The Seagate Pro 600 performs well in the mixed read/write testing, with an average slightly lower than the CloudSpeed 500 in the heavier mixed workloads.
The Seagate 600 Pro has a wide range of latency distribution in this test, with 3,131,077 I/Os (44%) at 10-20ms, 1,614,008 I/Os (33.7%) at 8-10ms, and 693,221 I/Os (14.4%) at 40-60ms.
Power consumption for the Seagate 600 Pro averages 3.21 Watts.
The Seagate 600 Pro averages 4,945 IOPS, nudging the CloudSpeed 500 for the win.
