Very fast transfer speed (58.6 MB/s)

Thanks, that helps in understanding your setup a bit more. My guess is that your ASUS RT-AC66R is making the real difference. I’ve been holding back on upgrading my router to an AC router, but I’ll have to put router on the planned replacements now. Since my highest speed N router from Netgear was already gigabit, I didn’t think I could get much improvement for wired connections by moving to an AC router, because I thought the only improvement would be on the wireless side. But now I realize that the benefit of a faster chipset does seem to make a difference even with wired connections. I already had the same ASUS router you have along with Netgear’s top AC router on my shortlist for many months. So when I do buy, it’ll come down to one of these two.

Interesting to know you have got comparable speeds between RAID0, RAID1 and JBOD. Thanks again for sharing these very helpful info.
