—> Western Digital product page
I needed an external USB HDD to put on my Airport Extreme anyway. I really like the idea of having time-machine making a backup of my Thesis and being able to share videos with my mac mini…
The price (109 €) is decent for a 750 GB USB HDD.
I hope “Smart and energy efficient – Turns itself on and off with your computer.”; also means that it will go into standby mode when not being used for some time.
UPDATE: It arrived and it seems to spin down when not used! (even with the laptop on and the drive mounted)
