Upon opening the packaging, you'll find one 2.5in hard drive in an aluminium enclosure all wrapped up in a shock-resistant rubber sleeve. You also get a 500mm USB 3.0 cable and a USB power-sharing cable for those stuck with underpowered ports.

Will not get lost in fog
Unlike some other manufacturers, LaCie doesn't offer their products in 'kit' form with an included USB 3.0 PCIe or ExpressCard 34 adaptor, so make sure to order one as to ensure you aren’t condemned to face eternity at 480Mb/s.
Folk used to carrying a 2.5in drive in a slimline enclosure may find it a bit of a shock to realise that the LaCie Rugged is quite a bit bigger, measuring in at 145 x 90 x 28mm - or approximately the size of a standard 3.5in hard disk. A 3.5in disk wrapped in fluorescent orange rubber, that is.
However, that being said, most of the space is given to allow room for the rubber anti-shock dampers so the whole thing is deceivingly light. Despite being somewhat larger than anticipated, the drive is actually very portable.

COMMENTS
While we're on the subject of ruggedness
can we have the person who came up with the WD 'My Book' enclosure taken out and subjected to all of those Mil-Spec tests, please?
Balancing a 3.5" HDD on its narrow edge and positively encouraging people to place it near their mouse hand may well not have been the greatest design decision ever. Based on 3 (so far) that I've encountered, they tend not to survive being toppled while spinning, and the form factor means it only takes a tiny nudge...
Did you read the review?
This is a bus powered drive that has no PSU but draws power from the USB port.
I have a LaCie drive that has a PSU and it's just a standard 12V affair it can be replaced for around £5
Fungus?
Military equipment is ruggedized against mushroom attack?
More irresponsible naming than Pocahontas' parents.
Rugged and Hard Drive are two things that should never be associated. This is still in a pretty flimsy case and I have suffered some pretty nasty data loss from one of these while it was in hold luggage transit.
Rugged my ass, the little big disk with its aluminium case is far far more reliable (crappy LaCie PSU aside, but that's for another story, already covered by previous poster) and with RAID0 will actually be able to make use of eSATA bus speed.
This line of rugged LaCie's should be outlawed for irresponsible marketing. And LaCie as a HD manufacturer is greatly over estimated. IMHO.
No bloody good...
If it comes with the usual crap PSU that dies just after a year and costs about as much as the drive to replace.
Yes, I do have a LaCie drive I can't use at the moment. How did you know?
