Working on the new MacBook Pro with fixed hard disk space, pretty much forces me to handle bigger projects with external drives. I often work with a slim external USB 3.0 SATA Drive, and for larger files where I need more performance I can work with Solid State drives, and for the fastest speeds I switch to a portable SSD Thunderbolt adapter.
The problem with always working with external drives is having the drive dangling around. I was searching for a simple (non-permanent) way to mount a drive to the back of my laptop screen, and came up with a new use for these cheap Super Sticky Dash Mats
Here are a few images below using my 'corny' dash mat mount. Obviously you want to work with a lightweight portable drive like the Seagate Slim (found here), but these mats are sticky enough to carry my Seagate Portable Thunderbolt adapter for true performance editing (found here).

Check out the holding power of these dash mats. That's a 5 pound weight (not even using full surface area) held vertically. That would be the equivalent of mounting 15 of my solid state drives together. [A Canon 5D DSLR weighs under 2 pounds] Definitely more than enough super strong holding power for just one drive.
These dash mats can probably be found at your local hardware or office store, but you'll find them cheapest on Amazon (click here).
