    I've been looking for an portable external HD for my 2012 MBA and stumble upon this today

    http://www.ebay.com/itm/Western-Dig...al-5400-RPM-/300753902160?var=#ht_1974wt_1374

    I know i have to reformat it for a Mac but what i was wondering is if the usb 3.0 function will work with the Mac? I ask this because on the Western Digital website, they have a separate "My Passport for Mac" hard drive but it is only USB 2.0, so i wondered if they didn't recognize the 3.0 functionality.

    Thanks

    just bought 2012 MBA, and I have a WD passport 500gb and a WD elements 1TB, though it looks one generation before, but with USB3.


    and i'm having terrible results with both for the moment :(


    another forumer has had the same problem, change the cable, seemed to fix the problem


    will see

    I bought the blue one from amazon last month, had to format it to work with my MBA and it works perfectly. Not sure if Its running with usb 2 or 3.0 though.

    I have the 500GB version of that drive and just formatted for Mac and it works fine at USB 3.0 speeds on my 2012 MBA. from what I can tell, the "Mac" version is just preformatted in HFS+ for you.

    you can make a speed test with this free app :

    As for my speed problems, the cable seem indeed to be the cause, and they have probably solved the issue in new batches :)

    thanks for that. Any ideas what speeds should be at 2.0 and 3.0?

    The cable that came w/ the 1tb blue one is rock solid. I have an older 500gb WD mypassport and that cable is definitely very flimsy.

    I have a 2012 13" base mba. I just tested the 2TB version of the WD passport with BlackMagic and got 85/85.

    wow that seems good. I have the same MBA, using the 1TB WD passport and getting speeds of 25/33

    What are the speeds they claim and what is USB 2.0 average speed?

    Informal real life results: it took 12 hours to put 1.4TB on to the drive using my late 2011 mbp, samsung 830 ssd from a firewire 800 external through usb 2 to the passport. Moving the same set of files (iTunes library if you're curious) via usb3 to a usb3 seagate 3TB using the mba, took a little less than 5 hours.
