Wowsers! Western Digital’s Thunderbolt My Book VelociRaptor Duo is all about the big numbers. 10,000 RPM platters, 2TB storage, 10Gb/s transfer (in both directions) and – if you daisy-chain it with other Thunderbolt drives – you can RAID things up to make them even faster.

Heck, even the price is impressive: $860. Ouch!

Mac OS  X Lion introduced the world to FileVault 2 Apple’s solution to full disk encryption. It is one of my favorite features in Lion, and it is definitely a welcome addition to Mac OS X. Just about anyone can use it to encrypt the startup disk on their Mac, but more importantly, they can use it to encrypt their USB thumb drives and SD cards. Why is that important?

It is important because USB thumb drives and SD cards are small and easily lost. If they are encrypted, you don’t have to worry about whether the content they carry falls into the wrong hands.
