I have a Mac so maybe no answer but..... I have all of my music, movies and photos (MMP) on a disk drive and play on (or through) my mac. What you said about RAID intrigues me. Is it possible to duplicate my MMP on another drive and have it always automatically be a duplicate drive? i.e. I record a movie on the drive I use, at the same time it records to another separate drive (or two). Rip once in a lifetime.....yeah.
