Raspberry Pi SATA HAT: Dual SATA HAT for Raspberry Pi 4

If your Raspberry Pi 4 doesn’t feature enough storage, HAT can help extend the Pi storage using SATA port HDD. Besides, you only need the Raspberry Pi and HDD powering for a 3.5-inch HDD setup. As a result, your PSU will provide over 65W power with just a 2X3.5-inch HDD. There is so much the Raspberry Pi SATA HAT can help you accomplish. Therefore, we will learn more about it, including its assorted models.  

NAS Solutions: Rock Pi SATA HAT

ROCK Pi SATA HAT is a hat for Raspberry Pi /Rock Pi 4. It features high performance with high-speed USB3.0 buses and SATA slots. Raspberry Pi 4 and Rock Pi 4 are useful Single-board computers in many applications.  

Similarly, the Radxa SATA HAT-like solution features a series of SATA expansions targeting the NAS complete solution for ROCK Pi 4 / Raspberry Pi 4. Besides, it comes in three modules, namely;

  • Penta SATA HAT; Usually intended only for ROCK Pi 4 and connected over PCIe bus
  • Dual/Quad SATA HAT; usually intended for ROCK Pi 4 / Raspberry Pi 4. It can operate with both boards and connect over two USB 3.0 flash drives.



To ensure it expands up to 5X SATA ports, the Penta SATA HAT employs the M.2/PCIe on ROCK Pi 4. Thus, for the users who may want to use the external disks, the devices adapt one eSATA and four internal SATA making the linking flexible.

USB-powered dual SATA HAT top board exploits high-performing dualistic JMS561. As a result, its four disks in the RAIDO approach offer up to 400MB/s of writing/reading performance.  



Case and Software Support for Raspberry Pi SATA HAT

The Case

The optional hat top board comprises a fully metallic case with Raspberry Pi OS, making it attractive. Besides, it supports the upper panels, including four 2.5-inch HDDs.  

Software Support

Powered SATA HAT features a Debian package for observing and regulating. Likewise, with a simple command, anyone using ROCK Pi 4 or Raspberry Pi 4 can connect the bundle.  


HAT for Raspberry Pi 4 helps to extend Pi storage even up to PD 65W power consumption. Besides, with a USB/QC power jack adapter, you can power both the Raspberry Pi 4 and the disk drives. Therefore, there is no need to worry about having a Raspberry Pi lacking sufficient storage.
