CAV drives for laptops?

Hi all,

is there somewhere a list that one can consult to find which drives use (Z)CLV and which use CAV for writing?

As I understand, CLV makes things considerably slower, so it would be useful to have this information about a drive before purchase.

From what I see however, a lot of vendors don’t mention this information, and even the official product pages of most manufacturers don’t actually include that piece of info in their specs!
