8K Random Read/Write
8K random read and write speed 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 Seagate 1200 measures 57,276 IOPS at QD256, while the Toshiba PX02SMF outperforms with an impressive 88,493 IOPS
Both SSDs exhibit a tight latency range during the 8K random read test.
The Seagate 1200 again leads in the heavy write workload test, with an average of 20,403 IOPS at QD256. The Toshiba averages 16,259 IOPS at QD256.
The Toshiba experiences significant latency variability, particularly with the heavier workloads.
The Toshiba PX02SMF again leads with the heavier read workloads, but begins to experience variability quickly once the write workload increases.
Power consumption for the 1200 averages 6.16 Watts during the measurement window, and the Toshiba falls slightly lower with 5.98 Watts.
The Seagate 1200 again leads in the efficiency test with an average of 3,320 IOPS per Watt, while the Toshiba clocks a respectable 2,858 IOPS.
