BTW - in a recent test of 2.5" high-capacity HDD, it was noted that SATA 
required significantly more power than PATA. Well 'significant' to a laptop on 
battery, anyway.

Given that single-drive setups seldom stress even UDMA 133 over the course of 
reasonable time spans, does anyone know if:

A) SATA 300 needs yet-again more power than SATA 150?

B) running down-shifted to SATA 150 might actually be a better plan anyway in 
some circumstances?

Easier to maintain data integrity comes to mind as well as power budget.

Just curious...
