Ask me what the most expensive laptop I have seen in my life, and I would answer back with any rugged line of laptops, like the Panasonic Toughbook. When I first spotted them at a local retailer back around 2002, it was the first time I saw a good combination of weight, performance, and -- get this -- an optical drive. Unfortunately, it was also the first time the price of a laptop alone made me take a second glance. At the time, I did not understand why the laptop was so expensive, until I realized what Toughbooks were. Panasonic started the line in 1997 as their line of rugged computers designed to withstand all sorts of extreme environment factors and mishaps, while still being able to fully function as well as any other laptop. Fast forward to today, the same thing is found with other manufacturers like Dell. These computers' price tags are not small either, and come close to the trade-in value of the car I currently drive. The specifications on these machines are generally mediocre at best, yet their prices remain astronomically high. Of course, these are not aimed at the general public, as there are many different industries benefiting from these lines of laptops. On the other hand, you can see durability plus electronics equals an empty wallet, as you really have to pay to keep them protected from the elements and accidents. So as I review the Silicon Power Armor A30 today, an external USB 3.0 hard drive that can withstand drops up to three meters or almost ten feet, I can only wonder if this is a good combination of protection and performance. Were there any compromises Silicon Power had to make to keep it as durable as it is? Can it keep up with the rest of our storage solutions? And even more importantly, how does this compare with the ADATA DashDrive Durable HD650 500GB, an external hard drive I evaluated in just the past week? All of these questions, and more, will be answered in today's review.
