For several years, there is this type of DVD burner, but so far they were just too expensive for me. Now I have a time to beat at a used unit at short notice and I was not disappointed. Especially the backup to the media runs in conjunction with an SSD under Windows 7 x64 with very loose and after I no longer have the DVD-Berg, who has previously accumulated when performing a backup. So after 30 years of making the computer the backup really fun.
