you cna never be sure what you are going to get wiht a pacific digital drive I first purchased one when they were rebaging the yamaha 12X only when I bout the PD 12X it turned out to be some brand I had never heard of "lite On" I was at first very unhappy it wasnt a yamaha. but after using the drive I was quite pleased with it. so I also purchased the 16X and 24X PD's when they came out both being Lite ons. then when their 32X came out I bought it thinking it was another lite on. only it turned out to be a cendyne and that POS was built so far out of spec it wouldnt even fit in the drive bay of my computer. it went back to the store and from then on I bought lite on's online from newegg.
