data recovery and hard drive articles

This project consists of 5 articles about data recovery (how does a hard dive work, what is a typical hard dive error, How does RAID work ect. ). The articles should be 500 to 700 words in length. These articles are for SEO, but there will also be people reading them, so it should make sense. If you find inspiration form different sources, then I don't want to see any copy paste, to make sure I will run all articles though copyscape. I want real content, and therefore also proper English. When the articles are paid for all rights will go to me. Examples of titles of articles, just so you know what it's all about: How does a hard dive work? How does RAID work? Typical errors of hard drives! What is data recovery? ect. (Please post REOV in the start of your PM, so I know that your bid is not a standard bid, and so I know you have read this) I will chose a couple of good bids and ask you to make a "test" article on 200 words, and if I like what I see. Then I will choose you to make the 5 articles. Please note that if I am happy after the 5 articles more work will be on its way. Please PM your bids for 5 articles, just a heads up we where thinking 3-5 USD a article (payment will be through GFA escrow service)
