Portable High-Performance SSD

Not impressed. Waited eagerly for it to arrive which took about a month then tried it to back up my laptop files. It was terribly slow compared to the USB HDD that I had been using and some errors where evident (photos now just black squares) fortunately I have other backups. Won't be using it for secure storage but to transfer stuff between phones. I'll buy another HDD for longer term use.

Does not save directly from my phone, so got to try saving the long way round

I copied my laptop's data onto it. It took over 24 hours. Documents, videos and music. My laptop is 2TB storage so I needed more storage. When copying was finished, only the docunents were there. No music or video files. Bad.
