Your answer should be from the review itself and should not contain extra words, and should not be a combination of different spans. If there's no direct answer to the question, answer with a part of the text that is the most relevant to the question. See the examples for clarification.
Teacher: Now, understand the problem? Solve this instance: review: This is a plug and play external hard drive for my Macbook Pro running OSX, Mountain Lion. It doesn't require an external power source which makes this the perfect companion for the business traveler, mobile office professional, videographer or photographer.Startup was fast and my laptop recognized it immediately. The unit is sleek and compact making it great for transport in a backpack or "Man-Purse". The hard drive runs quietly and there is not a lot of heat emanating from the housing.I do not use or have the need for software to run this hard drive.It's a great unit. Two thumbs up.
question: What is perfect for this unit?
