I have 4 8TB disks configured as 2 8TB RAID 1+0 volumes and formatted HFS+. One of the volumes benchmarks about 100MB/s slower than the other (the first of the two is faster). 480MB/s vs ~380MB/s.
Any idea why this might be the case? Shouldn't they have virtually identical performance?
I'm using the beta SoftRAID 6 driver and software.
Attached are pictures of the two volumes.

You have to understand the mechanics on disk drives. The inner volumes are significantly slower.
This is a physics issue.

@softraid-support interesting- I didn’t realize that volumes were created “outside->in”.
thanks!

Yes, fastest, to slowest. Disk manufacturers don't want users to see the performance on the inner tracks. Since users rarely fill disks, they don't.
