CineRAIDCR-H218 (Two Bay Portable USB 3.1 Gen. 2 Type C 2.5" Drive/RAID Enclosure) 2TB Capable, SSD 7mm to 9.5mm Height, 10GBs

What is the power supply for this? I'm using it on a usb-c that is not meeting the power requirements from the bus.

What cables does this come with?

Supported under linux? i have an older (healthy) hgst 2.5" 1tb 7200rpm and a samsung 860 evo 4tb ssd, could put both in non-raid without any ac power?

Could i put 2x 500gb samsung 850 evos in here in raid 0 and realistically achieve 800-900mb/s?
