The iPod classic Generation 6 continued the “classic” iPod design and used a 4200 RPM ATA-66 hard drive long after all other iPod models had switched to flash memory. The advantage to the spinning hard drive was that it could hold far more songs for a lower price.
The iPod classic Generation 6 offered a 80 GB or 160 GB hard rive capable of supporting 20,000 or 40,000 songs and 100 or 200 hours of video.
The iPod classic models use a 2.5-inch color LCD display with an LED backlight at 320×240 and use cases with either a silver or black anodized aluminum front and a chrome stainless steel back (previous models used white or black polycarbonate fronts). The iPod classic models were the first full-size iPod models to not be offered in white.
The larger case also allowed for long battery life: 30 hours of music and 5 hours of video for the 80 GB model and 40 hours of music and 7 hours of video for the 160 GB model.
The software included a Cover Flow option for selecting albums, and three games were bundled: iQuiz, Klondike, and Vortex.
