Completely unable to find any substantial difference in writing quality when comparing high speed and low speed burns, I'm still interested in finding devices, which allow burning CD-Rs at slow speed for a completely different reason. The "best" you can get in this regard on currently available drives, is the Plextor PX-891SAF-PLUS – but note that it is not actually a Plextor (at least as far as I know it is a Lite-On). This overly expensive thing (which probably has nothing in common with previous "real" Plextor drives) offers write strategies of 8x for CD-R and 4x for DVD±R. This is slower than common, but faster than it should.
For normal CD/DVD writing I very much doubt low speeds are needed or helpful – at least I could find no evidence. This might have been different in the early 2000s. But, as said above, I'm still on the hunt for old writers supporting 4x for CD-R. Currently I have only about 5 of them. Only two of them I'm willing to lose by tinkering around (the others are pretty rare and valuable). Read-only drives from that time frame are much more common than writers. Hard to find at good prices. Those old models have the additional advantage, that they feature a chipset consisting of multiple dedicated chips: For firmware (and data processing to the host machine), for the AD conversion as well as EFM and Reed-Solomon decoding and for servo controlling. Currently available drives more or less do all the stuff in one single chip (and the PCB of a modern drive is minuscule compared to one from the late 1990s/early 2000s).
Flea market brought up a pretty early instance of a DVD±RW drive this time. For CD-R thankfully the speeds 8x and 4x popped up. The only fairly "new" drive beating this would be the Plextor Premium 2, which includes a 2x CD-R write strategy. No way I'm gonna pay several hundred €€€ for such a thing (let alone multiple of them).
I haven't mentioned the name of the mystery drive I bought Saturday. Why? Well. See for yourself in the first picture. How I would like to work with the professionals for once…

Few people will care about this blog entry. Maybe @Alexander1970 and @SylverReZ?
Edit: Original packaging and bundled software (hopefully I made all software serials unreadable – else somebody could say I'm distributing "highly interesting warez")
