WD PiDrive Node Zero – A low-energy hard drive coupled with a Pi Zero

The WD PiDrive Node Zero is a compact, all-in-one unit that includes a WD PiDrive connected to a Raspberry Pi Zero through a custom adapter board with 2 USB ports. This unit offers an affordable, low-power storage node with an onboard computer. Suitable for data logging, offline analytics, and applications where stand-alone operation are required due to network or privacy-related limitations restrictions.

The PiDrive is Western Digital Corporation‘s low-energy hard drive, designed particularly for the Raspberry Pi. It replaces the regular SATA III port with a micro-USB connection. It’s a compact combination of USB hub, Pi Zero and 2.5″ hard drive that could easily be VESA (Video Electronics Standards Association) mounted behind a screen or tucked away in a neat case.

The WD PiDrive Node Zero comes with a 4GB microSD preloaded with a customized version of the popular NOOBS (New Out of Box Software). On first boot, Raspbian gets installed in the primary hard disk and not on the 4GB microSD. The SD card boots the device, but you run it from the hard drive. So you do not have to switch between the two drives.

Western Digital suggests this device as:

Ideal for video recording, data logging, offline analytics, and applications where stand-alone operations are needed because of network limitations or privacy/security restrictions.

As the Pi Zero has neither onboard WiFi module nor ethernet connector, you have only two options for taking a PiDrive Node Zero online. Either add a USB-to-Ethernet adapter and hook up to a wired network or use a USB WiFi dongle to access WiFi connection. The newer Pi Zero W has onboard WiFi chip. So, you can replace the Pi zero of WD PiDrive with a Pi Zero W to gain easier WiFi access.

The WD PiDrive Node Zero kit comes with the following:

  • WD PiDrive 314GB
  • Raspberry Pi Zero
  • USB Adapter board (PCBA) with full sized ports
  • 4GB microSD card (with preloaded software)
  • Mini HDMI adapter cable

Once you are connected to a network, you can make amazing DIY projects like data logging weather station, JukeBox with something like Volumio or PiMiusicBox for streaming your whole music collection, mini-DLNA and Samba file server, mobile backup device and much more.

Conclusion: Out of the box, this product runs fantastically. The inclusion of the customized NOOBS installer was a smart move and makes installation a lot easier. Disassembling the unit is not at all user-friendly and the lack of networking option is a limiting factor. But it remains a charming and handy piece of kit.
