I don’t know about that, I have an old slim DVD burner by Delock, so it was rather cheap, but that thing is sturdy as hell. Those things are slim drives in external cases, after all. Nothing tinfoil about the case, though I wouldn’t (and didn’t intend to suggest to) put a heavy weight on a naked caseless slim internal drive itself.

Also, the disk is fixed tightly in place in slim drives, even if the walls were to be slightly bent, I doubt there would be an effect on burn quality because the disk isn’t going anywhere and the laser is articulated.

Throw the paperweights on there, I say.

If that’s really your concern, put a paperweight on the drive?
