Just want to confirm -
I have 6x8TB drives (TB3 to TB2, Mac Pro 2013, Thunderbay6)
If I make a new volume RAID5 20TB, "Drive_A" - and then another new volume on the same disks RAID5 20TB "Drive_B", Drive A should be the faster of the two volumes on average?
AJA write/read
A
720/897
650/913
691/925
Avg: 687/911
B
571/782
606/791
698/785
Avg: 625/786
Does this seem typical?

More or less, yes.
The inner area of a disk platter has less surface area, so there is less room to store sectors. Disks do not store information equally per track like an LP album, they pack sectors as tightly as possible across the platter.
This means the density of bytes is lower and throughput will be slower.
