Review on Blackjet VX-2SSD USB 3.1 Gen 2 10Gbps Thunderbolt 3 Compatible Dual SSD Docking Station: UASP Support, RAID 0/1, JBOD for High-Speed Storage & Archiving by Tyson Burch

So far so good on my 2017 iMac with macOS 10.13. Speeds seem pretty darn fast, I've switched from G-Dock ev Thunderbolt 2 which might actually be a bit faster - I'm only using JBOD so can't comment on RAID. One note: at the moment it seems that when you remove a drive in JBOD, both drives are removed and reinitialized (not reformatted), they just need to be remounted. A little annoying.
