This page has been created to serve as an entry point for discussing Network-Attached-Storage (NAS) options for home and small business use.

There are a number of dedicated hardware options out there, which are devices with between one and five hard drive bays that can be plugged into any LAN as a standalone device with a web interface for managing access. Depending on the price they can have options like dual Gigabit ethernet and eSATA connections and offer various types of RAID configurations through the web interface. See the NAS-central wiki for an overview of vendors with dedicated devices.

The problem for us with these dedicated devices is that they are expensive and use proprietary software for hard drive administration, so we need to look at options using off-the-shelf components that can run the organic design server package for administration. We are currently developing a web interface based on RecordAdmin to manage users and groups as well as shared files, so we can just use that instead of proprietary web interfaces.

Requirements

First, let's look at what our NAS solution needs to fulfil:

  • Quiet
  • Low power consumption
  • High transfer speeds (1GB ethernet or eSATA options)
  • Compact case
  • Using off-the-shelf components
  • Ability to run OD server

Options

The best option for a compact and quiet case is to use a MicroATX case which can fit 3x 3.5" drives, which would allow us to set up RAID 5, which means that we can sustain the loss of a hard drive and just rebuild the Given our requirements, we need to find a MicroATX case with a motherboard that supports eSATA and Gigabit ethernet and then add 3x 3.5" 1.5 TB hard drives for 3TB of NAS storage - no video card, sound card or DVD burner are required.

The other option is to use a Fit PC with attached USB enclosure to give us a "poor man's NAS" with very low power consumption, but no fancy RAID configuration and limited to to fast ethernet speeds. We will also need to have a USB enclosure for every drive attached. In the case of Fit PC 2, we could utilise full USB 2.0 speed due to the Gigabit ethernet connection.
