    X835 3.5" SATA HDD Shield Hardware   Software
    Product Description 
  The X835 is a 3.5" SATA HDD expansion board focused on providing a bigger storage solution for your Raspberry Pi B/2B/3B/4B. The board is a great way to give a desktop look, as you can connect multiple 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 X835, 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 X835 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.
