Got a 2TB (really about 1.89) WD MyPassport USB 3.0 HDD over the holidays at an awesome price. Used it today with Macrium to image my main partition containing 200GB+ and the other recovery, uefi partitions. Took about 35 minutes. I love this!
It reported I/O at the end of 1GB/sec read and 800MB+/sec write average.
I expected hours from 2.0 experience. Advancement in tech is wonderful!
