Peety.....you are blowing my mind

As much as I value having photos backed up, I would favor a system that minimizes your efforts while on vacation. I would think having the photos saved on your cards and 1-2 drives would be sufficient. But that is me.

I recently picked up a 2 TB external hard drive USB 3 compatible that was advertised on this site. It is great to have the 2 TB, but transfer speeds are still around 40 MB/sec, I assume because of the write speed of the drive (USB powered). An SSD may be much faster, which would make your life easier while on vacation.
