Right... Just got my Toshiba/Samsung 1912 from newegg.com. This drive is also very very quiet. Doesn't have riplock, has region free firmware, and doesn't cache for EAC. Asus on the other hand doesn't have any of that. The only thing it has is being quiet.
I have the NEC 3520A for burning. Sounds real quiet burning. But I don't use it for reading, so I don't know how loud this thing gets during read.
