My Passport external HD

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

http://www.ebay.com/itm/Western-Digi...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.

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

well based on WD's website:

Up to 5 Gb/s in USB 3.0 mode and
up to 480 Mb/s in USB 2.0 mode

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.
