I just bought a brand-new Seagate Passport 4TB External drive, and used it to back up some data. However, it took over 12 hours (this is just copying a file directory straight onto the drive through Windows Explorer - not using any encryption or included backup software). This is MUCH slower than the 3-4 hours it took to copy the same exact data onto a Seagate 1TB External drive I had purchased over a year ago. Both transferred the same data, on about the same day/boot of the PC, and are using the same USB port, and the same USB 3.0 cable - why was the newer, bigger drive so much slower to transfer data?!
The older 1tb drive lists a transfer speed of 120mb/s... The newer 4tb drive doesn't list the transfer speed... Not on the box or in the documentation, or any of the sites advertising it. Even Seagate's website itself doesn't have any information about the speed - Am I missing something obvious here?
