讀的時候的確是蠻吵的，
而且已經刷了quite drive firmware，
可是這版韌體裡面有提到，
說這是讀壓片才會有差，
如果是讀燒錄片的話，
不管哪一板韌體都是一樣全速的，
這是上面寫的：

RIPLOCK enabled for quiet DVD playback on your PC. Please note, this will only playback slow on pressed DVD’s. DVD-R and +R media will still play at full drive speed. This is a feature of the STOCK NEC firmware.
