I went from using LiteON to Samsung for a while because LiteON's drives were unnecessarily spinning up to full speed. Samsungs' drives are nice and quiet, but recently I've found that they couldn't handle DVD recordables as well as their predecessors and other drives. I've tried recorded discs in other identical-model Samsung drives though and they had the same problem, regardless of firmware.
My Samsung drive also has a tendency not to drop discs onto the tray properly and jam the drive during the eject sequence, though admittedly I think that my Samsung drive is on the way out. It has also acquired the habit of jamming up while loading a DVD movie, rendering the system partly inoperable, not recovering, then on reboot the drive sometimes disappears from the list of drives.
Recent LiteON drives don't seem to have the same problems as the old ones did. <tries a random disc> yep, I can just hear the drive as if it was an additional very quiet fan, but that's it. Within 10-15 seconds of the initial spin-up, the disc has spun back down presumably due to an idle time-out. I just tried a DVD disc in there as well and it spun up a bit louder for about 2 seconds, then down to the 'v.quiet fan sound', then idled quickly again. I watched a DVD with it the other day and I like my system running extremely quietly (silence would be nice), and I wasn't thinking "damn this drive is loud" while watching the film like I used to with drives about 5-7 years ago.
My LiteON drive is the iHAS124.
I used to have a Pioneer slot drive about a decade ago, though back then drives got used a lot more than they do now, and it died after (I think) 2 - 4 years of use.
