I was bulk ripping CDs a few months ago and was running multiple SCSI drives to increase my throughput. The current Linux SCSI drivers will lock up the bus when you insert a disc and ruin any transfers already in progress on another drive. You'd think something like that would have been resolved at this point.

An actual SCSI device? And you're complaining about "by now". How old of hardware are you using? "By now" fixes are included in modern hardware on USB.

I have a number of Plextor CD-ROM drives that are more desirable than DVD-ROM for CD audio extraction. I have one USB Plextor but they command a high resale price. The point is that basic bus management should be sorted out and it clearly isn't.

If you're pulling a digital bit-stream off a disk then why does the reader matter?

A lot of CDs aren't in perfect condition, either because of scratches or things like https://en.m.wikipedia.org/wiki/Compact_disc_bronzing. When faced with damaged data, the quality of the drive and its firmware will influence whether the data stream corresponds to the original content or not.

Thanks for the explanation - I misinterpreted the OC to be about audio quality rather than just trying to recover data from damaged media.

Given a perfect CD the drive is probably not going to have significant impact, but for an audio CD that's been exposed to real world conditions there's a bunch of ways the drive can make a difference to the recovered data.

A little interested! What exactly are FIFO buffers?
there was a slew of software hacks in most cd burning suites that'd attempt to deal with that problem across the industry.
believe it or not : time dependent FIFO buffers are capital H Hard. Or at least they were back then.. I suspect the damage done by poorly constructed FIFO buffers now is just more hidden, not exactly lessened.
