I recently bought two of them during sales at Staples.
They work fine. The only problem I ran into was with the drives having trouble waking from sleep.
I used WD SmartWare to turn off the drives' internal sleep function, and I unchecked "put hard disk(s) to sleep when possible" in Energy Saver. My machine itself sleeps after 1 hour, so the internal hard disk sleeps with it. The external drives are left alone.
I don't keep the drives connected to the machine all the time, so there's no issue with them not getting any rest. 😀
