RAID 0 8k Random Read/Write

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 workloads.

 

The four-drive array of Seagate Enterprise Capacity v4's provides 759 IOPS at 256 OIO, and expands to 1,460 IOPS with the eight-drive array.

Once more, we note more variability with the addition of several drives. This variability is offset by enhanced performance.

The eight-drive array moves up to 1,245 IOPS from the 641 IOPS provided by the four-drive array.

The Seagate v4 exhibits a propensity for random write workloads in general, and scaling becomes more effective with heavier write workloads.
