The LaCie Little Big Disk Thunderbolt (1TB SSD) ($999 list) is the latest version of the aluminum-clad thoroughbred series of external solid-state drives (SSDs), keeping a single user's data easily accessible at a moment's notice.

Expensive per GB; Requires included AC adapter for use (not bus powered).

Electronics of all kinds aren't really built to withstand much in the way of knocks or extreme weather, but a special breed of portable hard drives exists to serve this very purpose – to withstand the everyday tumbles and adverse weather without sacrificing your precious data.

Not the smallest drive I had, but certainly the toughest. The drive is very well built, and has excellent transfer speeds. The setup was a no-brainer, and the drive has been working like a charm for a bit more than a year now, and survived plenty of trips.

Great for backing up just not very portable

Long lasting; great service

Expensive; if this drops then all your data will be lost

My first boss was a real fanatic about backups, and taught me to always compound the odds in my favor. MIL-spec ruggedness is a way of doing that and, along with the availability of lots of space for files, made it pretty easy to pick this drive out of the many other models available on the market.

bus-powered; rugged; USB 3.0; fast; AES 256-bit encryption; Thunderbolt interface

so far none

Bought this one for my son because he needs a good reliable hard drive for backup and travelling. The one I purchased for myself has been around the world a few times. I would definitely recommend this drive to anyone.

This mobile drive is compact yet very tough. The design is well thought out for protecting data on the drive - both electronically, by encrypting and password protecting files, and physically - rugged metal case and strong rubber bumper. The USB3 speed is great. I couldn't be happier.

I purchased this drive in March of 2015 for my girlfriend, and it sat on her desk as served as storage for her videos and recorded music (she is a working musician). The drive worked without issue for several months, until this month (August 2015), when the drive refused to spin up.

Drive enclosure is metal, with a plastic caddy and a pretty good SATA->USB interface; Speeds were reasonable; Rubber bumper is well made and seems like it would serve it's purpose

I am giving this drive one star due to LaCie's choice of drive vendor, Seagate, in this case; Please read the "other thoughts" section for an explanation

This is a terrific little hard drive. I work from home, but also travel a lot and so I needed something that I can plug into my iMac in my studio, but also my MacBook when I am on the road - the rubber housing makes this EHD bullet proof!

Durable; Lightweight; Plug and play
