Raid 1+0 (Why is my Write speed faster than my Read??)

I have a Thunderbay8 x 8 (WD Red Pro 18TB) drives. I created a Raid 1+0 volume. The speedtest shows my Write speed is 1200 MB/s and Read is 550 MB/s. My understanding of Raid 1+0 is that read performance should be 2x the write performance. Am I missing something?

Try AJA System test at the app store (free)

Settings:

16bit RGBA codec

64GB file size

5K or higher video resolution

 

Its more consistent. What do you get?

If slow, click the graph button. Are there major dropouts?

You are right, the AJA System test is much more in line with the performance I was expecting to see. Thank you!
