Much better than saying "laptop burners are crippled, live with it?" Well, you explain why, the burner is slow, but it still is.
I have a dvd/cdrw combo on my D600 laptop, when using cdrecord to burn
cds the burning process starts at x10 speed, after 168MB it goes up to
x16 speed and only after 502MB it finally reaches x24 speed.
That's normal behaviour for certain cd writers. It's a question of the
write strategy. This one is named Zone-CLV, which means that it writes a
constant linear velocity in certain zones (0-168, 168-502, 502-end in
your case).
There's also CAV which means constant angular, which means that the drive will rotate at the same speed throughout the whole burn process. And thus the writing speed will increase with every written MB.
Some (my ABIT for example) seem to run the same speed end to end, I would call that constant data rate, but I know there's a standard term. Yes, the drive sounds as if it changes speed constantly, it really seems to be doing that.
