I am ready to buy external USB media for storing my backups & images. I am considering 2 options: (1) an external 256gb SSD USB 3.0, or (2) a 256gb 3.0 flash drive. Surprisingly, option 1 costs only a bit more than option 2. Ergo, cost is not a factor. Option 1 is *reasonably portable* but I can carry option 2 in my pocket. Which of the 2 options do you think I should choose, and why?
