ROCK Pi Dual/Quad SATA HAT is an addon HAT designed for Raspberry Pi 4. It utilizes the high speed USB3 buses on Raspberry Pi 4 and providing a complete NAS solution based on Raspberry Pi 4. It has the following features:

  • Up to 4x HDD/SSD, support 2.5inch or 3.5inch SSD
  • Utilize two independent USB3 buses on Raspberry Pi 4
  • Type C power input with USB PD support for both 2.5inch SSD and Raspberry Pi 4(v1.1 hardware)
  • 12V DC power input for 2.5 and 3.5 inch HDD and Raspberry Pi 4(v1.2 hardware)
  • External standard ATX power supply support for 3.5inch HDD
  • Support HDD suspend mode
  • Support software RAID 0/1/5
  • Optional PWM control fan for HDD heat dispatching
  • Optional OLED display for IP/Storage info

Other hardware needed

  • Proper power adapter(Check power options below for more info)
  • 2.5inch or 3.5inch HDD/SSD
  • Raspberry Pi 4 or ROCK Pi 4 with OS running
  • optional 7+15P SATA cable(For 3.5inch HDD or extending the length)

Model Number

Since the Raspberry Pi 4 changes the form factor(swapping USB and RJ45), we need different USB connection adapter. The ROCK Pi 4 shares form factor with Raspberry Pi 3/3B+. Below is the different model number:

QF3 Quad version for ROCK Pi 4, Raspberry Pi 3/3B+
QF4 Quad version for Raspberry Pi 4

Power Options

Power consumptions for typical disks:

Power Consumption
2.5 HDD 3 ~ 5W
2.5 HDD 5 ~10W

Note: the table above is for reference, check your disk label for the exact power consumption. More info can be found here.

Option 1: Powering from Raspberry Pi/ROCK Pi 40P GPIO header

The Raspberry Pi GPIO +5V can provide up to 1.5A power, the typical SSD is 3W power consumption. So you can drive up to two SSDs directly powering from Raspberry Pi with good 5V/5A USB C power adapter.

The ROCK Pi 4 GPIO +5V can provide up to 4A current. You can drive four SSD/HDD directly if your power adapter can provide > 35W power.

Option 2: Powering from USB C or DC Jack on SATA HAT


For V1.1 hardware revision, we use USB C for the power input on SATA HAT with PD/QC support. Same as option 1, you can choose USB PD power adapter > 35W to driver up to four 2.5inch HDDs and Raspberry PI at the same time. 3.5inch HDD powering is not supported from the USB C port.


For V1.2, we changed the power jack on SATA HAT to 12V DC because the 12V power adapter is much cheaper than USB C PD adapter. Also, users want to power 3.5inch HDD with power adapter instead of ATX PSU. The 12V DC jack is 5.5x2.1mm diameter. You need at least 12V/3A to power four 2.5inch HDD and 12V/5A to power four 3.5inch HDD.

Option 3: Powering from ATX PSU

If you plan to put the SATA HAT in a PC enclosure, then you can use the ATX PSU. Mostly ATX PSU can meet the power requirement. You need a ATX Floppy cable to power the SATA HAT and Raspberry Pi.
