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. Several workloads rely heavily upon 8K performance and we include this with each evaluation. Many of our Server Emulations below also test 8K performance with various mixed read/write workloads.
The average 8K random read speed of the Turbo SSHD weighs in at 596 IOPS. The Enterprise Turbo and MK1401 trail with 525 and 522 IOPS, respectively.
The average 8K random write speed of the Turbo SSHD is dominating at 508 IOPS. The MK1401 averages 443 IOPS, and the Enterprise Performance delivers 447 IOPS.
The Seagate Enterprise Turbo SSHD leads the pack again in our mixed read/write testing, enjoying a large lead across the various percentages.
Once again, the SSHD exhibits a lower latency distribution than the other HDD's.
Power consumption for the Turbo SSHD and the Enterprise Performance are very close, with 8.07 and 8.02 Watts, respectively. The MK1401 averages a miserly 7.29 Watts during the measurement window.
The Turbo SSHD delivers an incremental increase in IOPS-per-Watt performance over the Enterprise Performance 15K HDD.
