1) I wanted to make a backup of the hard drive of my home PC (photos, videos, music ...), equipped only usb2, using the software that comes with this external drive and aware that I could not enjoy the Transfer speed usb3 but this backup proved endless: after more than 24 hours, copying data 120go was far from over. I used to make a backup in usb2 with the free SyncBack another disk become too small for me now and I needed much less time ... So I uninstalled the NTI Backup software (although I had chosen this hard drive brand because of the software that came with, Based on the expert opinion) and reinstalled SyncBack instead. There is no picture: my backup was performed within hours without fault ... 2) I also regrets the lack of on / off button that would turn off the power without unplugging.
Otherwise, I have little perspective to assess the reliability of this record but I'm used to the Toshiba brand and I have never been disappointed in the past.
