The Good Large capacity, USB 2.0, FireWire 400, and FireWire 800 support; bus powered; valuable bundled backup software; all data cables included.
The Bad A bit bulkier and heavier than competing compact external hard drives. Power switch is hard to reach.
The Bottom Line It's big, and it's fast. The OWC Mercury On-The-Go offers fast throughput via USB 2.0, FireWire 400, and FireWire 800, and it's the biggest compact hard drive, at 500GB, you can get right now.

OWC Mercury On-The-Go (500GB)
Laptop hard-drive capacity hit the 500GB mark just a few months ago. The OWC Mercury On-The-Go is an external version of this new breed of 2.5-inch hard drives. Aside from having the largest storage capacity among compact external drives, the Mercury offers a handful of other features. The drive supports USB 2.0, FireWire 400, and FireWire 800, and it performed very well in our tests. Its design offers some geek aesthetic with a clear plastic casing that lets you see the internal hard drive and the circuit board. Even though the drive is not the most compact among its peers, its capacity, good performance, and versatile connections justify its $350 price (which translates into about .7 dollar per GB).
Design and features
The OWC Mercury On-The-Go ships in a very simple package that includes a travel pouch, a software CD, data cables, and a power adapter. According to OWC, the power adapter is required for all connection types except FireWire 800; however, we found out that it is only necessary when you use the drive with USB 1.1. We tried the drive with several computers that have USB 2.0 or FireWire and never had to use the adaptor.
