Recently, I bought a new MBP largely to do audio recording and editing "on the go." My first real road test of my little setup will be coming up in about three weeks and before I go, I want to get a portable external HD to back-up all the raw recordings as I go along. I will be doing a lot of recording at high resolution (generating large files), so the more capacity on the external, the better. I see that WD has announced a 1TB USB-powered portable in their "Passport" line, but Amazon still lists it as "not yet released." The B&H website seems to suggest that it may be coming in "3-7 days." Does anyone know how soon we can expect this? Has a release date been announced? (I can't find one...) I'll need some sort of traveling HD for my upcoming road gig, and I'm just trying to figure out if the 1TB model will be available within two weeks or if I should go ahead and get the 500GB model now.
