The Apacer is a good machine, mine has worked flawlessly for two years. Why more people don't use their system is beyond me. Backing up all my photos is essential, and the Apacer makes it as if I'm creating negative files of my shots. I can't see storing all my photos on my laptop or harddrive--it slows done the machine, and if there were ever a system crash, all my work over the past couple of years since going digital would be gone. The Apacer is a great solution for backing up.
