Sequential Read and Write
Our Sequential read/write workload is centered on 128K transfer sizes at QD32. I ran testing for the Buffalo TeraStation 6400 with the included drives over a 5Gbe network.
With all three RAID modes hitting the limit of the 5Gbe connection, performance tops at 592 MB/s read.
Write performance is slightly lower; 373 MB/s for RAID 0, 378 MB/s for RAID 5, and 285 MB/s for RAID 6.
Workload testing shows fantastic results with Database reaching 20K IOPS. The other four workloads hovering between 1700 and 2000 IOPS.
RAID 5 gives Database another 10K IOPS with File Server right behind a touch under 6K IOPS.
RAID 6 favors Database at 8K with the other four between 1 and 2K IOPS.
