ROCK 5 > Guide > How to use M.2 E-key to SATA breakout board
ROCK 5B has a M.2 E Key with PCIe 2.1 1-lanes, SATA, SDIO, UART support.
It can use a breakout board to make M.2 E-key to SATA.
Requirement
- ROCK 5B
- M.2 E-key to SATA breakout board
- SATA Cable
Hardware connection
About SATA power cable, yellow is 12V, red is 5V, and black is GND.
If you use SSD, only 5V power from 40 pin are required as follow.
If you use HDD, 5V and 12V power supply are required as follow.
Here I supply 12V via digital power supply, 5V is still supplied from 40 pin.
Software configuration
Add one line to file /boot/config.txt. Like this.
dtoverlay=rock-5b-sata
And then execute command.
update_extlinux.sh
Reboot the device, you would see your devices with command lsblk.
rock@rock-5b:~$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:48 0 149.1G 0 disk mmcblk1 179:0 0 14.6G 0 disk ├─mmcblk1p1 179:1 0 512M 0 part └─mmcblk1p2 179:2 0 14.1G 0 part / mmcblk1boot0 179:32 0 4M 1 disk mmcblk1boot1 179:64 0 4M 1 disk
You can test read and write speed with command dd or fio, but only if you protect your data.
