SentrySafe has teamed up with Maxtor to create a line of fire resistant and waterproof USB hard drives, the better to protect your data in a disaster. The drives can withstand temperatures up to 1,550° Fahrenheit for 30 minutes and can be submerged in water for up to 24 hours.
They're maddeningly expensive for the capacity—$260 for an 80GB version—but have undeniable appeal to industrial strength data solution fetishists like myself.
Sentry is also selling a safe with slots of DVDs with a USB cable passthrough to a small drive inside. In fact, it looks like all these units may use 2.5-inch drives instead of full-sized 3.5-inch ones—that would explain the lack of capacity.
