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.

ABOUT THE AUTHOR - Tyler Bernath

Growing up in a small farm town, tech wasn't around, unless it was in a tractor. At an early age, Tyler's parents brought home their first PC. Tyler was hooked and learned what it meant to format a HDD, spending many nights reinstalling Windows 95. Tyler's love and enthusiast nature always kept his PC nearby. Eager to get deeper into tech, he started reviewing.
