"In today's market, the "big idea" behind having multiple hard drive comes with a certain niche attached - convenience, security, or cost. Naturally, the convenience of being able to quickly replace a dead drive and return the array to working order, the security of being able to take the data with you, or the cost of effectively having multiple computer systems, with only the hard drive being changed. Call this last notion bygone if you will, but some of the people I spent my past college days with followed these ideas to a T. Take for example, one of my classmates - outside of the classroom, he designed and maintained databases. In that respect, having two hard drives, with the interest of always having a working machine, and avoiding the inevitable debacle, when a classroom coding experiment goes horribly wrong. In that spirit, these two products received today - the T5-SS Hard Drive Reader and xAGE-N99-SAU/US HDD Docking Station will be viewed as a complete solution - or what you can utilize to have the freedom of two systems, but maintain the data portability of having a partitioned drive. Let's start simple, with the T5-SS."
