The drives arrived quickly and were well packaged with lots of protective bubblewrap. As these are NAS drives there's no commercial packaging which is just fine.
The Synology NAS had no problems picking the drives up and making the storage available. The longest part was waiting for the NAS to provision the drives.
This is my second pair of 4TB drives, with the first purchase in December 2014, and I've had no issues. Fingers crossed these will continue the trend.
Don't forget to grab your serial number and register the drives with Western Digital directly.
Packaging is perfect, small cardboard box with enough bubble wrap inside it to stop it from moving around and cushioning it from any impacts on top of an anti-static bag to make sure that the drive arrives in working order.
Since I started working sporadic 12 hour shifts, being able to buy my drives online and mailed to my door has been a god send. Thanks WD and Amazon!
