I am looking for a 25-50 GIG blue-ray external drive, usb3. I want to take years of home pictures and transfer to a blue-ray DVD. Can anyone direct me to a few blue-ray external devices that support different blue ray DVD media types The more I read the more I am getting confused? Am I wrong that the burner will be able to read different DVD, CD media types? Had read the blue laser is best for long term storage on DVD. Not sure if true or not.
