Introduction

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
Support USB Direct Access Mode from PC
Optional PWM control fan for HDD heat dispatching
Optional OLED display for IP/Storage info

Software support

We provide an install script to help you get the SATA software that works in Raspberry Pi 4B.

curl -sL https://rock.sh/get-rockpi-sata | sudo -E bash -

Just copy the command above and paste it into the terminal and press enter. If you want more settings, check out section Software Configuration at the bottom of the page.

NAS support(optional)

OpenMediaVault

Install: Installing OMV5 on Raspberry PI's

Troubleshooting:

1. OMV WebUI only shows two HDD's

This is likely because JMicron controllers incorrectly report identical serial numbers and other data which confuses various systems.

You can “fix” this by adding a rule to /lib/udev/rules.d/60-persistent-storage.rules after the entry for “Fall back usb_id for USB devices”:

   # Fix Quad SATA HAT disk serial number
   KERNEL=="sd*", ATTRS{idVendor}=="1058", ATTRS{idProduct}=="0a10", SUBSYSTEMS=="usb", PROGRAM="/root/serial.sh %k", ENV{ID_SERIAL}="USB-%c", ENV{ID_SERIAL_SHORT}="%c"

You will also need to create /root/serial.sh containing the following:

   #!/bin/bash
   /sbin/hdparm -I /dev/$1 | grep 'Serial Number' | awk '{print $3}'

And you need to add execute permission to the file via the following:

   chmod +x /root/serial.sh

Finally, install the hdparm.

   sudo apt-get install hdparm

This will ensure that unique paths are created based on the serial number of the actual drives and not the hat.

RTC support(optional)

In version 1.2, we added RTC functionality. If you want to use the RTC, you will need to install a battery (socket next to the fan). For Raspbian, you can do this to enable RTC:

Add dtoverlay=i2c-rtc,pcf8563 to the /boot/config.txt and reboot. Execute sudo hwclock -w after reboot.

Model Number

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

Model	Description
DF4	Dual version for Raspberry Pi 4
QF3	Quad version for ROCK Pi 4, Raspberry Pi 3/3B+
QF4	Quad version for Raspberry Pi 4

Detail of the HAT board

Power Options

Power consumptions for typical disks:

	Power Consumption
SSD	<3W
2.5 HDD	3 ~ 5W
3.5 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 a 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

V1.1 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 drive up to four 2.5inch HDDs and Raspberry PI at the same time. 3.5inch HDD powering is not supported by the USB C port.

V1.2 SATA HAT

For V1.2, we changed the power jack on SATA HAT to 12V DC because the 12V power adapter is much cheaper than the USB C PD adapter. Also, users want to power 3.5inch HDD with a 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 an ATX Floppy cable to power the SATA HAT and Raspberry Pi.

Software configuration

Just edit /etc/rockpi-sata.conf, take it effect by below command

sudo systemctl restart rockpi-sata.service

Below is the default /etc/rockpi-sata.conf, which you can modify according to the comments

```
[fan]
```

# When the temperature is above lv0 (35'C), the fan at 25% power,

# and lv1 at 50% power, lv2 at 75% power, lv3 at 100% power.

# When the temperature is below lv0, the fan is turned off.

# You can change these values if necessary.

```
lv0 = 35
```
```
lv1 = 40
```
```
lv2 = 45
```
```
lv3 = 50
```
```
 
```
```
[key]
```

# You can customize the function of the key, currently available functions are

```
# slider: oled display next page
```
```
# switch: fan turn on/off switch
```
```
# reboot, poweroff
```

# If you have any good suggestions for key functions,

# please add an issue on https://rock.sh/rockpi-sata

```
click = slider
```
```
twice = switch
```
```
press = none
```
```
 
```
```
[time]
```

# twice: maximum time between double clicking (seconds)

```
# press: long press time (seconds)
```
```
twice = 0.7
```
```
press = 1.8
```
```
 
```
```
[slider]
```

# Whether the oled auto display next page and the time interval (seconds)

```
auto = true
```
```
time = 10
```
```
 
```
```
[oled]
```

# Whether rotate the text of oled 180 degrees, whether use Fahrenheit

```
rotate = false
```
```
