Whoa!
Who said U160 SCSI was faster than SATA? That's a common farce!
In fact, it's the whole reason why SAS (Serial Attached SCSI) is coming
about. SAS can even use SATA drives.
I don't think that's is a good comparison at all. You're changing too many
variables. Especially when you're comparing ultra-high density SATA drives
to typical, lower-density U160 SCSI drives. Latency might be better, but
throughout is clearly not.
It all depends on your application.

Depends on the app, but you might be correct for many applications.
And, just because I'm curious, "hardware RAID SATA" by what controller?
