On the Road: a 1TB Bus-Powered SSD for Backup
Photographers on the go should have a backup drive, which should be stored separately from the computer (consider a backup drive in the same bag as the laptop, and the bag is stolen).
On the road, I clone my laptop internal drive to the external backup after every day’s shooting download. I prefer SSDs for speed and durability.
OWC now offers a 1TB SSD for just $449 which can go into an external bus powered mini case (about $34).
