=== Raid Setting===
Please read [[Raid Instruction]] firstly. You can freely choose the four RAID modes supported by NASPi Gemini by setting the jumper cap. Strongly recommend to use the same brand and capacity HDDs when use RAID Mode.
＊'''Warning''' : Please backup your data before setup and switch, otherwise you maybe lost your data.
1. Inert HDDs to X885 shield and fix it.
2. Please connect the X885 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 X885 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 model
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]]

<span class="tb_red ">Warning about power supply:</span>
# Don't use that adjustable voltage power supply.# Don't use the same power supply used on LED strips.
The above two are absolute garbage power supply, can not be used!!!

===About SSD/HDD===
* Older SSD/HDD drives with less efficient flash media may not perform as well as newer drives.
* A microSD card is required for forceing the Raspbian OS to use the HDD/SSD for its "root" partition

==FAQ==
A: In theory, there is no limit to the HDD capacity for NASPi Gemini 3.5, but related with the operation system. And the engineer only test it with max 10TB HDD, so we write 10TB in the product information,
Q2: Why only one SSD/HDD is recognized?
Please '''exit the RAID mode''' and check again after '''entering the PM mode(clear raid mode)'''.
More details please refer to '''Set CLEAR RAID mode''' of [[NASPi_Gemini_3How to Configure RAID Setting] Q3: Does the X885(NASPi Gemini 3.5) support one 2.5" SSD and one 3.5" HDD? A: It is not recommend, but if you need to use one 2.5" SSD and one 3.5#Raid_Setting|Raid Setting]]" HDD, it can only be used in the '''PM''' mode, not support RAID.
