I have both the UltraPlex (32X) and UltraPlex 40max (40X), and they are
pretty equal when it comes to disc spinning noise. The UltraPlex 40max
do seem to vibrate even less than the UltraPlex, though both drives are
close to non-vibrating compared to other fast drives.
And by the way, the UltraPlex 40max comes both in a SCSI2 and SCSI wide
version, not only wide.
I've decided to get one of these two units and I'd like to know if there are
any "Real World" performance gains for getting the wide vs. narrow one? Or
are they identical for all intents and purposes?
