I got this 4 Terribite LaCie drive says LRDOPS3 & sn# NL2A24HW on bottom. Came with a cord that says USB 10 SS. Plugged it into TB port on back of Imac Pro and it took 12 hours to copy a 1.01 Terrabite folder from a partition on the LaCie 2Big 8. When I got this mac I also got a the LaCie 2Big 8 2 sled drive box and I copied the same folder from a 2 Terribite Seagate drive in my old 4 sled Firm Teck SATA box hooked up to the USB input of the LaCie 2Big box via the esata to usc superspeed cable adapter in about 1 hour. What's wrong with this picture, if it's that slow why did it come with the SS USC type C cable and connectors??? I am surely doing something wrong or is it just this drive that slow???
