This would be for Hi-Res music (.dff files) so I think the speed advantage offered by the JetDrive Lite vs. a MicroSD card is not so important, right? I believe the choice comes down to a cost (JetDrive Lite is about half the price of a Nifty/microSD combo) vs. my question about will the JetDrive Lite not being completely flush drive me bonkers? Unfortunately I do not know anyone with either of these and cannot see it in the flesh. Looking at the 128gb option for a late-2013 15" MBPr. Thanks. P.S. I saw SanDisk announced a prohibitively expensive (for me at least) 200gb microSD for $400. Any news on whether a 256gb JetDrive Lite (or another alternative) is on the horizon?
