I use Acronis to make disc images. When i make CD's the write speed is 48x. But if i make an imgae from 1 HD to another HD the write speed seems to be 48x also. Is this normal? I should think that from HD to HD the speed would be much higher. A 5Gb image without compression needs 12 minutes to be made from HD to HD. I have a Plextor CD reader/writer (48 speed), a Maxtor 80 Gb with 8 Mb cache (6Y080P0) and a Maxtor 60 Gb with 2 Mb cache (6Y060L0).
