you introduced unit number conflicts -- they were not part of discussion
before. please provide an example of two master drives on one IDE
channel -- this is the same technology level, esp. considering it's age
(and that of SATA)! furthermore, where's the IDE/ATA/... bus with seven
or 14 devices?

when comparing SATA to any SCSI, then go SAS -- same topology.

otherwise this discussion is like (foo) 'hey, the french got ``accents''
in their language -- imagine what they can do, on a linguistic level,
with them!' and (bar) 'yo, but the cars they build are crap!'.

hm, where's written that SATA was defined before SAS was?

furthermore, one can attach SATA devices to a SAS environment, and not
vice versa. so you claim a guy only speaking english more
multilinguistic than a guy who speaks english, spanish and perhaps
another language -- and is a fabulous translator, btw. weird.
