I just got one, and this drive very "silent" , read, write, even tray open and close, I almost foget it is in my computer.
I owns pioneer dvd-117, toshiba sd-m1712, sony DRU-500a, and plextor 1210s (SCSI), are not compare able to this new "preimum" drive.
I am so happy to have this drive, I make a good choice on it because I return Lite-On LTR - 52246S 52x 24x 52x and exchange to this one.
The only down side is this drive made in China, but we have no choice. All of the plextor drives now are Made in china, even in Japan, people can not find one made in Japan. Hope plextor can do much better quality control in China.
