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

 

Raspberry Pi 4 and Rock Pi 4 are useful Single-board computers in many applications. 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.

Similarly, the Radxa SATA HAT-like solution features a series of SATA expansion that targets 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.

 

ROCK Pi SATA HAT: Penta SATA HAT

 

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.
