I need a 500gb FW800 drive for keeping my photos on to be used for editing with Lightroom. I'm looking for an external drive that's faster than USB. Any recommendations. I'm looking at the G Drive mini for $140, but that's expensive compared to what I can get USB for (my 2TB WD Elements was for $80 so 500gb seems relatively expensive). But I guess I'm willing to pay a premium for FW800.
