I have about 500 gigs of movies music and photos I would like to move this to a separate storage off of my 24 inch iMac so i have more power and space for video editing. While speed is important for photo editing and video playback it is not everything to me. I am highy confused by RAID and know I will mess it up. I have researched DROBO for storage and just want to know if those whom complain about speed are just on a much higher level and looking for more than me. Also seems like there are reliability issues. It seemed much cheaper was thinking about JOBD set up with TowerRaid TRUT5. Then I could probably buy two and use one to back up the other. Thoughts? My needs are simply to expand my music and movies and keep it safe and secure. While making the backing up process as easy as possible. Best programs that auto copies new data over. Any one know?
