Conclusion:
For those wanting the functionality of a 2.5" hot-swap hard drive caddy, with some added points in the portability and looks departments, you might want to take a look at the Silverstone RVS01 I reviewed here today. It not only offers exceptional performance, but easily allows you to hot-swap drives while remaining portable at the same time. It's certainly worth the $32CDN if you require this type of functionality and "on the go" use from a hard drive enclosure.

Pros:
Ease of drive swapping
USB and E-SATA interfaces
Durable build
Great performance

Cons:
I'd like to see an easier way to access the ports without having to open the main enclosure cover
