Hard Drive question

[iash]

what's the difference between 500 GB 5400 rpm SATA vs 750 GB 5400 RPM hard drive?

[David (PassMark)]

Exactly 250GB.

What if "Drive 2" is not SATA?

Exactly 250GB.

That's assuming the 750GB drive is also SATA... If it's an external USB drive or possibly an old-style IDE internal drive, the capacity difference would be exactly as David said, but the transfer rates would be different (SATA is likely to be the fastest).
