Are you looking for a tiny portable hard drive for doing Time Machine backups on the road? I do a lot of traveling with my MacBook Air and don't often get a chance to back it up to the 1 TB monster at home. Although there are several other diminutive hard drives on the market, when I saw the My Passport Studio line of portable drives announced today by Western Digital, I ordered one. After all, the case matches my AirBook!
Available in 160 ($129.99), 250 ($189.99), and 320 GB ($219.99) flavors, My Passport Studio drives are about 3.2" x 5.0" x .71" (81mm x 127 mm x 18 mm) in size and weigh a featherweight 6.4 ounces (.18 kg). The drives are bus powered -- USB 2.0 or FireWire 400 -- so there's no need to tote a power brick when you're traveling. They're formatted as HFS+ Journaled, requiring Mac OS X 10.4.11+ or 10.5.2+.
The drives are available from Western Digital, and through a variety of online and brick-and-mortar stores. The 250 and 320 GB drives are showing back-order status.
Thanks to Denver pal Mike for the phone call tip this morning!
