I think (but could be wrong... ) that the old flopticals where the so called bernouille drives :
http://en.wikipedia.org/wiki/Iomega_Bernoulli_BoxThey used to be competition to the SyQuest drives.
LS-120 came later, as a counterpart to zip drives
I have had an unused LS-120 for years, without any media so never tried it.
