Best Large Laptop-Drive Upgrade?

[mrlynn]

Number Two Son Nathan is complaining again about lack of HD space on his 2011 13" MBP. He's got a 340GB drive in it, and doesn't want an external (carries the computer everywhere), and he doesn't want to give up his optical drive for a second HD. I was wondering about one of the large 'hybrid' drives that OWC sells, e.g. one like this:

which would give him both more space and more speed. Good idea?
