In the name of science, or in actual fact solely for our own amusement, we've paired up two unlikely suspects in the world of external hard drives. IOSafe's latest effort, which is a mammoth beast and claims to be indestructible, and Freecom's Hard Drive XS, which claims to be one of the world's smallest USB 3.0 drives.

We wanted to take them out and put them in fun and kooky situations, since they are an unlikely pair and thus excellent candidates for a sitcom pilot. However, the IOSafe is just too bloody fat and heavy to carry around so we had to leave him at home and just take the Hard Drive XS to the park to go on the swings instead.

Try as we might to stop the IOSafe from working, we couldn't manage it. It's basically a house, but you can't keep bedrooms and kitchens in it, you can only keep 500GB of space in it. We pushed it down stairs, tried to drown it, set fire to the bugger, heck, we even tried to smother it with a pillow in its sleep but it would just keep on working. Very frustrating. It's the Rasputin of hard drives. We treated it like a conman would treat his elderly bride on the brink of the beyond, we treated it like a resented red-headed stepchild and we even treated it like it was a Middle Eastern country with oil and we were America. Nothing would stop this beast from ticking along fine.

Considering its hefty size we'd have thought it would fit more than 500GB of space in it - that's how these things work, right? To be fair, models start at 500GB and go up to a massive two terabytes. Other than the novelty of its indestructible build, it performed well and we had no problems with installing or using it, aside from lifting it onto a desk. Luckily we have a forklift loaned out as a review sample that we'll probably never get around to, crisis averted. 

We're surely not the target market for the IOSafe, though. Rarely in the London suburbs do we have earthquakes or natural disasters, so our hard drives are likely quite safe as they are.
