NiuBi Personal Cloud 1 (NB-PC1) is a network-attached storage (NAS) device specifically engineered to run free, libre, open source software (FLOSS). NB-PC1 has all the functionality of any commercial, proprietary NAS, but at a much lower cost and with the transparency, reliability, and accessibility advantages that come with using FLOSS.

Why a NAS?

Whether you’re a developer or a digital artist, chances are you have a lot of essential data, from music tracks to application code. So you probably already know that data loss is a fact of modern life, and backing up your data is the surest way to prevent it. You could use an online service for backups, but doing so exposes you and your data to a wide range of privacy, security, legal, and financial risks beyond your control. For example:

• What are the data limits and how much does more storage cost?
• Who really owns the data? Does the online provider gain some license to use your data?
• What kind of security is protecting your data? How can you audit that security?
• What kind of changes will the online provider make to their terms of use?
• What people (e.g., employees of the online provider) or organizations (e.g., governments) could also gain access to your data?

All these questions and more make a strong case for using not only a NAS, but a NAS over which you have complete control - a FLOSS NAS! Enter NiuBi Personal Cloud 1.

NiuBi Personal Cloud 1 can be used for a wide variety of applications, including:

• network storage and backup
• file server
• home media server
• download server
• web server
• remotely accessible private cloud

NB-PC1 offers increased information security, easier collaboration, and less administrative mess compared with SaaS solutions and other NAS devices.

Comparisons

There are hundreds of NAS devices out there, but none of them except NiuBi Personal Cloud 1 are designed from the beginning to be open hardware and run FLOSS. The table below shows two of the most comparable NAS devices and how they stack up against the NB-PC1.

Enclosure Design

The minimal enclosure design is a major factor in making NiuBi Personal Cloud 1 small, inexpensive, and energy efficient. Though we love the aesthetic of the enclosure, keep in mind the universal truth about NAS devices: they are best placed near your wireless router and viewed from the command line or web interface.

Air Flow

The fact the mainboard isn’t fully enclosed allows for better airflow and fanless operation (though the mainboard can accommodate a small fan if you want to add one). No fan means much less build up of dirt and dust - few things compare to the inside of a fan-cooled PC that hasn’t been opened in years, whereas we’ve never seen a dirty free-standing printed circuit board assembly.

Heat Sinks

In addition to the enclosure’s great airflow, its anodized aluminum side plates help dissipate heat away from the mainboard.

Drive Size

NB-PC1 is compatible with 2.5" drives, which means it has a small physical footprint and can work with a wide variety of SSDs in addition to the usual array of HDDs. NB-PC1 is not compatible with 3.5" drives, but a future version might be.

Free as in Freedom

NiuBi Personal Cloud 1 is 100% free of binary blobs. Check out this campaign update to see some of the backstory of how this is possible.

Libre Software

NiuBi Personal Cloud 1 can run several popular FLOSS suites for managing routers, NAS devices, or just general computing. These are some of the main suites the NB-PC1 can run:

Debian

Yep, the NB-PC1 can run Debian.

openmediavault

The openmediavault project is a Debian-based network-attached storage solution designed for home and small office user who lack deep technical experience or knowledge of setting up and and administering an NAS.

libreCMC

Billed as "the libre embedded GNU/Linux distro," libreCMC is a fork of OpenWrt that uses only libre components. Recently, our pull request for NB-PC1 compatibility was merged into the staging branch.

LEDE

The Linux Embedded Development Environment (LEDE) project is a reboot of the OpenWrt community. We’ve created a NB-PC1 fork of the LEDE project and plan on submitting a patch back to the main project once production of the NB-PC1 is underway. (It is unlikely the LEDE developers would accept a patch for a device not yet in production.)
