I have a Mercury Elite Pro Dual mini with dual 4TB drives in hardware RAID0 (the enclosure has a raid switcher).
I have formatted the drive to APFS.
I am connecting to a 2016 MBP w/TB using the supplied Thunderbolt 3 cable.
Could anyone tell me why I would only be getting MAX 250 MB/s read AND write, and how I could possibly remedy it.
The enclosure advertises up to 860MB/s
