probably one of the fastest on the market

Using a Mac Pro equipped with an internal SSD, the use (and purchase) an external SSD is justified or is necessary. Having, as a photographer, process or store files of up to 50 mg, I have several external SSD, constituting as many backups, and backups ... Backups!
I chose the Verbatim 128GB for its great price and for his breathtaking speed reading. I have made a selection of photos that I would particularly like and that I always keep on me (no one is safe from burglary, fire, etc.).
The other major quality of Verbatim's his extraordinarily small size combined with a very low weight. Suffice to say that three or four thousand pictures always find their place at the bottom of a pocket.
