There’s portable and there’s portable: the smallest of the drives top out at 1TB, and the biggest, which are really more of a plain ol’ external hard drive variety (though I suppose they’re still portable) top out at 2TB.
They all come in three colors, should that type of thing matter to you.
Of course, without a USB 3.0 motherboard there’s not going to be too much of an improvement over USB 2.0 drives, but Samsung says that, at their fastest, the drives are able to transfer a 25-gig file in four minutes.
No prices yet, but they’ll be available in the springtime, specially April.
Happy trails, etc.
