==Foreword==
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]],[[X832]], [[X829]], [[X822]], [[X880]], [[X883]], [[NASPi Lite]], [[NASPi]], [[NASPi Gemini 2.5]]etc. From only supporting single hard disk to support dual hard disks, from complicated installation to simple installation, now a new Raspberry Pi ANS storage kit - NASPi Gemini 3.5 (support DUAL 3.5" HDD) is released. Hope you will like it!
You can refer to [[GEEKWORM NAS Family]] to know more.
* Supports hardware JBOD, RAID0(striping), RAID1(mirror), Normal mode
* Supports mode select via jumper setting
* PlugandplayPlug and play, no drivers needed
* LED blue indicator indicates each drive status
==How to Power==
* Power supply: 12Vdc +/-5% , ≥5A≥3A, via DC 12V IN Port of X885, recommend to [[PSU60 | Geekworm DC5521 12V/5A Power adapter US/EU plug]]
* Ports & Connectors: DC jack - 5.5x2.1mm
'''Important Note: Please use high quality power adapter, the low quality PSU may damage the X885 board and not recognized the HDD.'''
<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==
Q1: What is the max hard disk's limit?
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?
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 [[How 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" HDD, it can only be used in the '''PM''' mode, not support RAID.
