The LaCie Rugged Thunderbolt external hard drive is a rugged, portable hard drive for when you are on the go. It is bus powered so you do not need to plug it into an additional power supply, it supports both Thunderbolt and USB 3.0. This particular version of the LaCie Rugged is the hard drive version, there is also an SSD version as well. For those wondering, this is Thunderbolt 1.
The hard drive in this is only 5400 RPM. But transfer speeds are very fast still and for 1 TB it isn't very expensive if you want a portable drive. Add on top the fact that this is more durable than most portable drives, it has shock protection for up to a 5-foot drop, and it is also water and dust proof. I own several of these drives and have never had an issue with them. Highly recommended.
The drive comes with an integrated Thunderbolt cable and an IP54 dust and water-resistant cover for the USB 3.0 slot.
You can buy the LaCie Rugged Thunderbolt drive on Amazon for only $169.99; http://amzn.to/1WN4OIl
