20 years ago I lost a digital shoot because of a hard drive. Never again. These days I have standardized on G-Technology products and I feel safe. Nope, not a spokesman for them, I am just a satisfied customer.
G-Technology Workflow.
In the upper left is the G-Technology EV Dock. It consists of two 1 terabyte drives that are docked with the computer with a Thunderbolt connection. What makes the drives so versatile is that they also have a USB 3 connector. Most of my shooting is to a tethered Macbook Pro that saves my files to the internal hard drive and the G Drive at the same time. This is achieved with the program Carbon Copy Cloner. When I finish shooting I just eject the drive and plug it into the G Dock. The files are then copied to the big drive that is right below in the photograph that is below. This is a G-Raid Thunderbolt drive. It is formatted as Raid 1 so all of my files are copied to two drives at the same time for maximum safety. The G-Raid is my working drive and the Thunderbolt interface really makes Photoshop fast. I have another Large G-Raid under the desk for backup and two large drives that I rotate for offsite storage of backups.

No matter what drives you use always have multiple backups. The 3-2-1 method is what works the best and is simple to implement. Have your original media copied to 3 different hard drives. Have 2 different types of media in the workflow and have 1 set of your files that are stored offsite. You never know when disaster will strike.
My backup strategy has gone from floppies to zip drives, then to CD's, then DVD's to finally hard drives. That has been a lot of transitioning from one media to another but it is something that just has to be done to keep my work safe.
