Let’s say that you needed to store a large amount of data in a central location (I.E. directory) but the largest drive that you can afford and find for a reasonable price is a 400GB Seagate SATA drive.<\/p>\n
Unlike other OSes that I have used, Slackware has an awesome \u2018autoraid\u2019 capability that is idiot proof. Believe me! I\u2019m not only the president, I\u2019m also a client!<\/p>\n
