ROCK PI SATA HAT: The Best NAS Drive 2020 to Backup Data

Raxda’s ROCK Pi 4 single-board computer (SBC), powered by the Rockchip RK3399 Hexa-core processor similar to the NanoPi M4 SBC now gets a new extension add-on card that transforms the ROCK Pi 4 board into a home NAS device. The kit is composed of an add-on card and an optional tall plastic case that is specifically designed to hold up to five 2.5″ HDD/SSD devices.

The SATA HAT card is connected to the ROCK PI 4 board through the 40 pin headers. The Onboard SATA interfaces also come with an all in one connector for both power and data so it will be more convenient and you would not need to use separate cables. Naturally, also a small fan to cool the case will be included in the planned kit.

Rock Pi SATA HAT has 3 different models including 2 hard disks, 4 hard disks, 5 hard disks, etc. The 2/4 hard disk version supports both Raspberry Pi 4 and Rock Pi 4 at the same time. It uses USB 3.2 Gen1 transmission interface to connect with the development board. , Provide 2 or 4 groups of SATA terminals to connect the hard disk, and provide 2 additional USB 3.2 Gen1 to connect other devices.

Because the 5 hard disk version uses the PCIe transmission interface, it only supports Rock Pi 4. It provides 4 groups of SATA and 1 group of eSATA terminals. It can connect up to 5 hard disks and the maximum total transmission performance can reach 803MB / s.

The power output of the Rock Pi SATA HAT is input through the USB Type C terminal (supports PD and QC power transmission modes). In addition to providing the Rock Pi SATA HAT body and solid-state hard disk operation, the power can be distributed to the Raspberry Pi 4 through GPIO use. If you connect a conventional hard disk that consumes a lot of power, you need to input additional power through the ATX power terminal.

In addition to connecting multiple hard drives through the Rock Pi SATA HAT, users can also transform the Raspberry Pi 4 or Rock Pi 4 into a mini NAS with a control panel and a dedicated case. In addition to displaying the operating status of the hard disk and system IP information, the control panel can also perform operations such as fan control and shutdown.

SATA HAT Top Board

For Dual/Quad and Penta SATA HAT

To monitor the SSD/HDD´s and display some basic information of the NAS, the TOP Board was designed.

It provides PWM FAN control, IP address info and other details via the implemented OLED display and a button for selecting as well as powering the device off. This button can also be assigned to custom functions on request.

A ribbon cable connects the SATA HAT with the Top board.
