Although plugging in a drive instantly gives you more room to store your stuff, what it does not give you is redundancy for your precious data. When a single drive fails, your stuff is gone. Enhance Technology, a leader in external storage systems, fired over a solution called the T4H CR EnhanceRAID that is sure to please not only your appetite for speed, but also your need for data redundancy."
