Disk Speed Test, Sequential Performance and Workloads

For testing, we used the Thunderbolt 3 connection of the Atlas S8+. This was paired with our 2017 iMac Retina 4K. RAID modes tested were 0 and 6 to cover most use cases for this platform.

We start off with RAID 0 as standard. With DST we found 1228 MB/s read and 959 MB/s

Next, we move to test sequential performance with disk bench, from this we see 776 MB/s read, and 604 MB/s write consistently across three runs while random performance touches 27 MB/s read and 3 MB/s write.

Flipping over to AJA Systems testing, we use a UHD workload with a 16GB file size and the ProRes444 4 codec. This gives us 1193 MB/s read, and 903 MB/s write.

RAID 6 didn't drop much in performance thanks to the substantial processing power. Here we see 1156 MB/s read, and 908 MB/s write.

Sequential performance touches 767 MB/s read, and 605 MB/s write for RAID 6 with 27 MB/s random read and 3 MB/s random write.

Back to the UHD workload, we see a drop of 100 MB/s read going to RAID6 still reaching 1035 MB/s read, and 878 MB/s write.

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.
