Question about LaCie 2big Dock Thunderbolt 3

Works perfectly under OSCatalina 10.15.1 - new iMac set up again with recovery, everything OK - but I reset iMac to factory settings (crashes in eMail and Final Cut) - reinstalled PRG and transferred data from the LaCie with Time Machine - then it was really perfect.
The LaCie 2big has done everything perfectly and is always in continuous operation - I would buy again at any time.

I can confirm Cessico's answer unequivocally. Works 1A under Catalina 10.15.2.
I use the Lacie for Parallels virtual machine storage and as data storage. Caps perfectly and is fast. The only point of complaint is that the Thunderbolt cable supplied is very short. I got a 1 metre cable from Apple. This way I can store the plate comfortably under the desk on the body. Personally, it would be a little too loud on the desk. But I am very sensitive and not a yardstick for others ;-)
