Four drives deliver 418 MB/s, and eight drives brings that up to 817 MB/s.

The four-drive array experiences some turbulence as each load begins, but averages 418 MB/s at 256 OIO. Eight drives bring the speed up to 817 MB/s.

We observe the same interesting latency distribution experienced with RAID 0 during the sequential write workload in RAID 10.

Our percentage testing shows the eight-drive Seagate array providing some benefit to performance, but scaling is much lower than observed with random workloads.
