Any recommendations for a 2.5" HD enclosure for the MBA that doesn't need a Y-USB cable to run (one that can only run on one USB cable). I'll take recommendations for bundled HD enclosures but would prefer external enclosure recommendations. Something inexpensive on Newegg.com would be great. Thinking about pairing it with a 1 TB or 500 GB Samsung 2.5" HD [5400rpm]. Thanks.
