Overview

This X880 USB 3 to dual SATA Gen3 ports shield makes it easy to add high-capacity, high-performance external data storage to your Raspberry Pi 4.The dual SATA shield supports two 2.5" or 3.5" SATA hard drives with ultra-fast data transfer speeds and configurable RAID modes. This dual SATA shield delivers fast file transfer rates up to 5Gbps with USB 3.1 Gen 1 performance. It supports SATA I, II and III and is enhanced with UASP to maximize the performance and speed of your SATA III drives. The dual SATA shield provides an effective solution for Raspberry Pi 4 to store, access, back up, and protect important files.

NOTE:

The current X880 does not have standby function.(August 2022)
Please use the same type of hard drive,HDD+HDD or SSD+SSD； an error will be reported when using SSD+HDD.
We do not recommend using Samsung hard drives,Please use hard drives of other brands.
Not supported for use with the X735 Power Management Board or X708/X728 UPS board.

About creating an X880 NAS：

Plan 1

Raspberry Pi 4 Model B x1
2.5 or 3.5 HDD x2
X880 V1.1 Dual SATA Gen3 HDD Shield x1
X880-A1 A2 Board x1
X880-C1 Metal Case x1

Plan 2

Raspberry Pi 4 Model B x1

Please note: x880 is a hardware RAID. It supports RAID at the hardware level and does not require any software configuration. This has nothing to do with software, even if OMV does not support RAID settings;

Important!!

For better system compatibility & performance, Please format your HDD/SSD to Ext4 file system.

Raid Setting

[About Raid]

【RAID setup and Jumper setting】

＊Warning : Please backup your data before setup and switch, otherwise you maybe lost your data.

1. Install the HDDs

2. Please connect the X880 to your PC or Raspberry Pi board and keep power on

3. Switch RAID mode

Set the switch button to your preferred RAID mode(PM/RAID 0/RAID 1/SPAN) as per the RAID illustration table.
Press the SET button for about 5 seconds, and release it till the blue LED indicators starts flashing.
After RAID mode changed, please confirm that the PC can recognize the disk(s) properly and shows the right capacity.

or you can run the fdisk -l command to view the hard drive on raspberry pi OS when you connect x880 to raspberry pi board:

fdisk -l

You can found two hard drives if you select 'clear raid mode'(this is PM model)

fdisk: cannot open /dev/ram1: Permission denied
fdisk: cannot open /dev/ram2: Permission denied

or

You found only one hard drive if you select the RAID0/RAID1/SPAN model

pi@raspberrypi:~ $ fdisk -l
fdisk: cannot open /dev/ram0: Permission denied
fdisk: cannot open /dev/ram1: Permission denied
fdisk: cannot open /dev/ram2: Permission denied

fdisk: cannot open /dev/ram14: Permission denied
fdisk: cannot open /dev/ram15: Permission denied
fdisk: cannot open /dev/mmcblk0: Permission denied
fdisk: cannot open /dev/sda: Permission denied

4. Set CLEAR RAID mode (PM, factory default setup)

Press the SET button for about 5 seconds then and release it till blue LED indicators starts flashing.
After above processes, the setup for CLEAR RAID is done.

[NOTE]

Once you set the RAID mode successfully, you need to partition&format&mount the hdd/ssd, so that it can be recognized by your Raspberry Pi OS. please refer to How to View/Partition/Format/Mount HDD/SSD

How to Power

Power supply: 12Vdc +/-5% , ≥3A, via DC 12V IN Port of X880
Ports & Connectors: DC jack - 5.5x2.1mm

Important Note: Please use high quality power adapter that with inner protection with X880, the low quality PSU may damage the X880 board and not recognized the HDD/SSD.
