You can’t write a tough-gadget roundup without including IoSafe gear. The $250 IoSafe Rugged Portable external hard drive will house the data you can’t fit onto your 64GB LaCie XtremKey. The Rugged Portable comes in 500GB and 1TB flavors (the latter costs $319), and is built to survive crushes (up to 5000 pounds), drops (up to 20 feet), and immersion (up to 30 feet for three days in either fresh or salt water). IoSafe says it should also survive 12 feet of immersion in diesel fuel, oils, hydraulic fluids, and aircraft fuels for an hour. Extreme temperatures and altitudes? No problem. The Rugged Portable also comes in an SSD version, which starts at $499 for 120GB and goes up to $2250 for 600GB.
