Many server workloads rely heavily upon 8k performance, and we include this as a standard with each evaluation. Many of our server workloads also test 8k performance with various mixed read/write distributions.

 

The average 8K random read speed of the PM853T is 52,511 IOPS; the 845DC EVO averages 52,731 IOPS; the Micron M500DC averages 48,034 IOPS at 256 OIO; and the Intel DC S3500 measures 44,444 IOPS. The PM853T and the 845DC EVO provide impressive read speed, but do not beat the M500DC by nearly as large of a margin as observed with 4k random read activity.

The two Samsung SSDs fall within a very similar latency envelope during the measurement window.

The M500DC easily leads with an average of 23,852 IOPS; the PM853T pulls in second with 8,561 IOPS; the 845DC EVO averages 7,112 IOPS; and the DC S3500 averages 6,937 IOPS.

Once again, the M500DC distances itself from the pack during pure write workloads.

The PM853T features resilient performance in mixed random workloads.

Power consumption for the PM853T averages 3.99 watts; the 845DC EVO averages 3.54 watts; the M500DC averages 4.77 watts; and the DC S3500 averages 3.75.
