None of my liteOn drives,(3), vibrate in the least. I suspect that mounting style may affect this.
I do not know , personally i will test and some other drives too ,before i make my mind …

I have in my hands one LTN 526 52x , i would do some tests and i will report my findings …
hello!
i got a ltn 526 too . nero info tool says it has only 120kb cache while aothers cdrom have 128kb. feurio device tester says it hasn’t a perfect qualily reading capability
i have done some stest:

Diagnosis:
Congratulations!
Your device nearly reads the data perfectly and with hardly any jitter errors
(The errors could be caused for example by a scratch on the CD)!
Result:
Operations carried out: 500, time needed: 52.037 seconds
Average time per operation (=seek time): 104 ms

what do you think about? and do you know the difference betwen ltn526 and ltn526S?From Feurio Device Tester [B]
i need a nice reader too… i would like to be able to back up games the fastest way and to rip audio discs just as fast.
right now i have a lite on 48246s (overclocked to 52246s) and a pioneer dvd-106s (16x40x).
i really believe that an extra reader would be useful…
