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.[[File:X882-Compare.jpg|700px|X882 V2.0 VS X882 V1.3]]

Geekworm NASPi2 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.

NASPi2 NASPi Gemini 2.5 is composed of three parts: [[X882]] dual 2.5" SATA HDD/SSD shield, NASPi2 NASPi Gemini 2.5 metal case and heat dissipation system(3Pin 4010 PWM fan with metal bracket). To get better heat dissipation of NASPi2NASPi Gemini 2.5, 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 or Type-C socket of X882shield, DO NOT power via USB-C of Raspberry Pi 4!!!, or you can't use the AUTO ON & Safe shutdown function</span>* Because the shielding of the metal casing will cause the <span style="color:red;">loss of 2.4G wifi signal</span>, we only recommend you to use Ethernet or 5G WiFi.

* Insert the SD card into Raspberry Pi 4 first before NASPi2 NASPi Gemini 2.5 installation start.* 5G WiFi is stable enough, recommend using Ethernet or 5G WiFi.* The Raspberry Pi4 board, 2.5" SATA SSDs/HDDs, power adapter are all not included in the packing list. '''Important!!''' For better system compatibility & performance, Please format your HDD/SSD to Ext4 file system.  We found that some newbies always ask strange questions about RAID; 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, 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

＊'''Warning''' ==How to Cooling?==* The NASPi Gemini 2.5 uses the same cooling scheme as the [[NASPi]], 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 chip.* NASPi Gemini 2.5 uses 4010 PWM cooling fan (<span style="color: Please backup your data before setup and switchred;">3 wires, support speed adjustment NOT reading speed</span>), can support automatic adjustment of speed according to CPU temperature, otherwise you maybe lost your dataneed to install the shell script.

<span style="color:red;font-weight:bold">Q1: Why only one SSD/HDD is recognized?</span> A: You found only SSD/HDD if you select the RAID0/RAID1 mode. 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_2.5#How_to_configure_RAID|How to configure RAID]]  <span class="tb_red_bold">Q2: What to do if HDD/SSD is not recognized?</span>

Q3: What is the thickness of a 2.5" HDD/SSD that can be accommodated for NASPi Gemini 2.5? A: NASPi2 NASPi Gemini 2.5 support Max <span style="color:red;">16mm</span> thickness 2.5" HDD/SSD; The thickness of 2.5" HDD/SSD on the market is generally 7mm, 9.5mm, 12.5 and 15mm，so you can choose the SSD/HDD according to your requirement.  Q4: Does raid inside of openmediavault function with NASPi-Gemini 2.5? A: NASPi-Gemini 2.5 support hardware RAID mode, please refer to above Raid_Setting, or you can set it to PM mode then let openmediavault control RAID setting.  Q5: What are the HDDs requirement when use RAID mode? A: Strongly recommend to use the same brand and capacity HDDs when use RAID Mode.  Q6: What to do if meet I/O error? A: First please check if you use the USB Type-C power adapter, if yes, please change to use DC power adapter topower via DC jack of X882 to test. The USB Type-C PSU maybe not enough to power the dual HDD/SSD.  Q7: Why only one SSD/HHD can be recognized? A: You choose the RAID1 mode, because it is a hardware RAID, so OS recognize only one HDD/SDD.  Q8: How to know if there will be HDD errors? A: If there is HDD error, there will be red led for the red marked part LED. [[File:Hdd.png|thumb|none|HDD error]]  Q9: RAID issue with OMV. A: The RAID mode is not tested with OMV OS. The OMV also supports software RAID, you can set the X882 to PM mode and test the software RAID of OMV.If you want to test the hardware RAID of X882, it can be connectted to WINDOWS PC for testing. Q10: How to replace a bad HDD? 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 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. If you use '''hardware RAID''', you can refer to the following steps:# '''Confirm the faulty hard disk''': If the HHD1 or HDD2 LED lights up red, it means that the HDD feedback S.M.A.R.T read error, it is recommended to 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 the same model and capacity as the original hard drive. # '''Shut down the NAS system''': to avoid 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. This process may take some time, depending on the size of the hard drive and the load on the system. PS: Although GEMINI also supports hardware RAID, we recommend that you use software RAID, which will bring certain convenience to later maintenance. The function of software RAID comes from the NAS software you use such as OMV.
