At the early 2017, we made a NAS storage solution for Raspberry Pi. Accroding to customers' feedback, we made a series of improvements, like [[X800]], [[X820]], [[X825]] V1.5, [[X825 V2.0]], [[X828]], [[X829]], [[X822]], [[X880]], [[X883]], [[NASPi Lite]], [[NASPi]], etc. From only supporting single hard disk to support dual hard disks, from complicated installation to simple installation, now a new raspberry pi storage kit - [[NASPi Gemini 2.5]] (only support 2.5" HDD/SSD) is released. Hope you will like it!

'Gemini' means dual, '2.5' means 2.5-inch SSD/HHD; Click [[GEEKWORM NAS Family]] to know more. ===Update History:=== * In December 2022, the NASPi Gemini 2.5 has been updated to a new version, it is the update of X882 V1.3 to X882 V2.0, remove the USB-C port on X882 V1.3, and update DC 5V power in to wide voltage input DC6-18V power in.* The new version completely solve the issue of I/O error.

Geekworm NASPi Gemini 2.5 is an ultra-compact dual 2.5 inch SATA HDD/SSD NAS storage kit with safe shutdown and auto power on function that specially designed for Raspberry Pi 4 Model B computer, it allows two pcs 2.5" HDD/SSD to working at the same time with your Raspberry Pi 4. Also support use with one single 2.5" SATA HDD/SSD.

NASPi Gemini 2.5 is composed of three parts: [[X882]] dual 2.5" SATA HDD/SSD shield, NASPi Gemini 2.5 metal case and heat dissipation system(3Pin 4010 PWM fan with metal bracket). To get better heat dissipation of NASPi Gemini2.5, it also support install Max 7mm thickness heatsink above Pi4, as we use the M2.5*11+6mm spacers to fix the PWM fan with metal bracket. There is space for extra heatsink installation on Pi4.

* <span style="color:red;">Power NASPi Gemini 2.5 via USB-C or DC jack of X882 shield, DO NOT power via USB-C of Raspberry Pi 4, or you can't use the AUTO ON & Safe shutdown function</span>

* Insert the SD card into Raspberry Pi 4 first before NASPi Gemini 2.5 installation start.

Please note:  # NASPi-Gemini 2.5 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.# Although NASPi-Gemini 2.5 also supports hardware RAID, even if BUT we recommend that you use '''software RAID''', which will bring a certain degree of ease of maintenance later on. Software RAID comes from the NAS software you use, such as OMV does not support RAID settings;

'''Note about PSU:''' Please use high quality power adapter==How to Cooling?==* The NASPi Gemini 2.5 uses the same cooling scheme as the [[NASPi]], or we only increased the height of the HDD/SSD may cannot copper spacer from 6mm to 11mm to allow a heatsink with a maximum thickness of 7mm to be recognizedplaced on the CPU chip. Since * NASPi Gemini can install two pcs 2.5 inch hard drivesuses 4010 PWM cooling fan (<span style="color:red;">3 wires, support speed adjustment NOT reading speed</span>), can support automatic adjustment of speed according to CPU temperature, it needs a high-quality power supply need to provide enough currentinstall the shell script.

==Cooling Solution==* The NASPi Gemini uses the same cooling scheme as the Refer to [[NASPi#Installation Video for X882 V1.3]], we only increased the height of the copper spacer from 6mm to 11mm to allow a heatsink with a maximum thickness of 7mm to be placed on the CPU chipif you are using X882 V1.* NASPi Gemini uses 4010 PWM cooling fan, can support automatic adjustment of speed according to CPU temperature, need to install the shell script3.

==User Manual=How to Install Script===*Software installation: Refer to [[X-C1 Software| how to install the shell script]], and this script is required to install to enable PWM fan runs and safe shutdown function.

1. Inert HDDs Software Guide of script installation, please fast forward video to X882 shield and fix it5 minutes 10 seconds.

3. Switch RAID mode* Set A: You found only SSD/HDD if you select the switch button to your preferred RAID mode(PM/RAID 0RAID0/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 RAID1 mode changed, please confirm that the PC can recognize the disk(s) properly and shows the right capacity.

or you can run Please '''exit the fdisk -l command to view RAID mode''' and check again after '''entering the hard drive on raspberry pi OS when you connect X882 to raspberry pi board: fdisk -lYou can found two hard drives if you select 'PM mode(clear raid mode)''(this is PM model)'.

Q3Q8: Does raid inside of openmediavault function with NASPi-GeminiHow to know if there will be HDD errors?

A: NASPi-Gemini support hardware RAID modeIf there is HDD error, please refer to above Raid_Setting, or you can set it to PM mode then let openmediavault control RAID settingthere will be red led for the red marked part LED. [[File:Hdd.png|thumb|none|HDD error]]

Q4Q9: What are the HDDs requirement when use RAID mode?issue with OMV.

A: Strongly recommend The RAID mode is not tested with OMV OS. The OMV also supports software RAID, you can set the X882 to use PM mode and test the same brand and capacity HDDs when use software RAID of OMV.If you want to test the hardware RAID Modeof X882, it can be connectted to WINDOWS PC for testing.

Q5: What First of all, it depends on whether you use '''software RAID''' or '''hardware RAID'''. If you use software RAID, there will be corresponding functional modules in the NAS software to do if meet I/O error?assist you in replacing the hard drive. After the HDD replacement is completed, the NAS software will automatically synchronize the data to the new hard drive.

A: First please check if If you use '''hardware RAID''', you can refer to the USB Type-C power adapterfollowing steps:# '''Confirm the faulty hard disk''': If the HHD1 or HDD2 LED lights up red, if yesit means that the HDD feedback S.M.A.R.T read error, please change it is recommended to use DC power adapter topower via DC jack replace it # '''Back up important data''': It is recommended to connect to a Windows computer and back up important files directly through COPY. # '''Purchase a new hard drive''': To ensure compatibility and performance consistency, it is recommended to purchase a hard drive of X882 the same model and capacity as the original hard drive. # '''Shut down the NAS system''': to testavoid data corruption or other unexpected situations during the replacement process # '''Start the NAS system''': After startup, the RAID controller will automatically detect the new hard drive and start the data synchronization and reconstruction process. The USB Type-C PSU maybe not enough to power This process may take some time, depending on the size of the hard drive and the load on the dual HDD/SSDsystem.
