==Overview==
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
* 2.5'' or 3.5'' HDD x2
* X880 V1.1 Dual SATA Gen3 HDD Shield x1
* X880-A3 Acrylic Plate x2
* SATA 7+15pin male to female HDD Power Extension Cable x2
* X880-C1 Metal Case 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.
==Features==
* Supports installation of X880-A1 A2 2.5 "/ 3.5" SATA SSD/HDD Shield
== Raid setupSetting==【RAID [About Raid] [[File:RAID-instruction.jpg|800px]] 【'''RAID setup and Jumper setting】setting'''】
＊'''Warning''' : Please backup your data before setup and switch, otherwise you maybe lost your data.
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 <code>fdisk -l </code> 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)

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/ram3: Permission denied fdisk: cannot open /dev/ram4: Permission denied fdisk: cannot open /dev/ram5: Permission denied fdisk: cannot open /dev/ram6: Permission denied fdisk: cannot open /dev/ram7: Permission denied fdisk: cannot open /dev/ram8: Permission denied fdisk: cannot open /dev/ram9: Permission denied fdisk: cannot open /dev/ram10: Permission denied fdisk: cannot open /dev/ram11: Permission denied fdisk: cannot open /dev/ram12: Permission denied fdisk: cannot open /dev/ram13: 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 Supply Requirement==* Power supply: '''12Vdc''' +/-5% , ≥3A, via DC 12V IN Port of X880* Ports & Connectors: DC jack - 5.5x2.5mm1mm <span style="color:red">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.</span>
==Packing List==
* 4 x M3 *18+6mm Spacers
* 4 x M3 *18mm Spacers
==X880-A1-A2==
The X880-A1 and X880-A2 are two pcs PCB boards with positioning holes that use to hold the 2.5" or 3.5" HDD/SSDs to use with X880 board togehter. Also include 2pcs SATA 7+15pin Male to Female Cables.
==Matching Metal Case==
===X880-C1===
Please refer to [[X880-C1]]. The X880-C1 is released on March 2022.
===X880-A3===
X880-A3 is the acrylic plates with 2mm thickness that use with X880-C1 metal case to hold the HDD/SSDs. It has the same function as X880-A1-A2, can replace the X880-A1-A2. But you will need 2pcs SATA 7+15pin Male to Female Cables.
