Cons: It's not 8TB holographic storage.
Overall Review: In regards to the 7200 or 5400 RPM issue, this is straight from Western Digital:
The Caviar Green drive uses the IntelliSeek technology, this calculates the optimum seek speeds to lower power consumption, noise, and vibration.
This means that this drive can run up to 7200 RPM.
