Will this work with USB 3.1 Gen 2 or Thunderbolt 2 or thunderbolt 4, USB-C?
Asked by: Mia
After another user posted this device was not compatible with USB-C, that's incorrect. I've backed up 2 laptops using Thunderbolt 3 with 1TB drives boot drives in under 6 minutes (about 1/2 used) and a 2TB drive with 1.5TB used via USB-C in 1 hour and 2 minutes. I'd been using an NAS Drive for backups that were taking over 6 hours for the 1.5 TB backups. Thoroughly impressed.
