Questions about this item

The enclosure requires a Thunderbolt 3 port on the host computer to reach the stated transfer rate.

Can I keep using my existing Thunderbolt 2 devices on the same chain?

Thunderbolt 2 peripherals work through an adapter, but the Pegasus M4 itself needs a native Thunderbolt 3 connection for full speed.

How do I verify the RAID array is healthy after setup?
