AD-724x VS AD-726x

What’s the differences between?
What you users have obserbed?
If you should chose, what’s would be your choice?
Do you know if Optiarc are planned to release a new family?

no differences?

I think someone mentioned that the AD-x26xS drives burn 8x with a CLV strategy while the AD-x24xS drives use Z-CLV starting with 6x and then switch to 8x. Not sure if this is really the case.
