128K Sequential Read/Write
The 128K sequential speeds reflect the maximum sequential throughput of the SSD using a realistic file size encountered in an enterprise scenario.
The Toshiba PX02SMF080 averages 823MB/s at QD256 in comparison to the Optimus with 586MB/s at QD256. It is important to note that the Toshiba PX02SMF080 is rated for 900MB/s of sequential read speed. We reached these speeds in FOB conditions, but our logging of read performance is conducted after our write testing is completed to assure steady state performance. During this period, we saw results as high as 843MB/s.
The Toshiba exhibits 128K write performance at an average of 371MB/s, 39MB/s shy of its rated speed of 400 MB/s.
The Toshiba PX02SMF080 has a wide range of variability in our mixed read/write workload testing, but manages to average higher speeds than the Optimus until we get into the 80-100% write workloads.
The Toshiba experiences an odd distribution of latency with 128K access that might point out a bimodal performance aspect. The Toshiba provides 444,137 I/Os (49.99%) at 100-200ms, and 224,746 I/Os (25.3%) at 1-2ms, with latency ranging from .2-.4ms to 10-20ms.
The Toshiba PX02SMF080 continues its miserly power consumption with an average of 5.97 Watts during sequential write testing.
The Toshiba provides 61 write MB/s per Watt.
