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 average 8K random read speed of the SuperSSpeed S301 comes in at 38,238 IOPS at QD256, which is comparable to the other SATA competitors.
The average 8K random write speed of the SuperSSpeed S301 is 31,116 IOPS at QD256. Once again, the pure random write speed of the S301 leads the pack by a fair margin.
The SuperSSpeed S301 SLC is superb when dealing with varying percentages of write activity. It drops less than 7,000 IOPS from a 100% read to a pure random 8K write workload.
The SuperSSpeed S301 provided 6,227,366 I/Os (66.9%) in the 6-8ms range, and the vast remainder, 2,597,695 I/Os (27.9%), fall into the 10-20ms range.
Power consumption for the SuperSSpeed S301 averages 3.98 Watts, which is very close to the Micron P400m.
The SuperSSpeed S301 averages 7,784 IOPS per Watt during the 8K preconditioning run.
