    For Raspberry Pi 4, X829 Dual 2.5" SATA SSD/HDD Storage Expansion Board


      Note: In December 2020, we replace the USB connector with USB cable.

      The X829 is a dual 2.5" SATA HDD expansion board focused on providing a bigger storage solution for your Raspberry Pi 4B. Its elegant and ultra-compact design allows two 2.5" HDD/SSD to be conveniently attached to Raspberry Pi 4. The board is a great way to give a desktop look, as you can connect two external hard drivers without having them "hanging" from the USB ports of your SBC.

      Knowing that our users might need more USB entrances, we added to extra USB 3.1 Gen1 ports to the X829, so the user can connect keyboards, USB sticks or even other external HDDs.

      If you are looking for building a Media Center or even a Network-attached storage (NAS), the X829 is the right board for it. You will be able to separate one hard disk only for operating system and the rest for media, games...etc.

      Please refer to X822 or X828 if you need dual SATA board for raspberry pi 3.
