    Benefits and costs of a Raspberry Pi

    What do you do if you have a bunch of spare (old) hardware, e.g. USB 2.0 hubs;-hard drives;-sticks and sd-cards? Well you can make a NAS file server with Raspberry Pi.

    The reasons for that:

    • Since the rpi doesn’t support more than USB 2.0, perfect.
    • USB hard drives are perfect for data storage and as primary root filesystem for the rpi
    • Power consumption is low, my current NAS 15-22W, the rpi with usb-stuff 1.5-2.5W
    • Online 24/7
    • Consume flash devices until they wear out on purpose, less drives :wink:
    • Because it’s fun.

    And how about the costs?

    • The newest Raspberry Pi ~ 40 EUR/CHF
    • A 16 GB micro SD ~ 8-10 EUR/CHF

    You will get the Rasberry Pi alone. It has no power supply. What about the power supply? Well I have a lot of power supplies from my previous smartphones, you only need a adapter with micro-USB connection, that’s it. Even IKEA has cheap power supplies for 10 CHF. The power supply should have an minimum output of 1.8A. See more on FAQ-Power. A network cable or WLAN adapter and you are ready to go. Additionally you might want a shell case.

    Spare old hardware

    Other purposes?

    • Apache HTTP server
    • Multimedia center
    • etc.

    Is that possible? Well, the latest Pi has following specs: Raspberry Pi 2 Model B

    • A 900MHz quad-core ARM Cortex-A7 CPU
    • 1GB RAM

    Like the (Pi 1) Model B+, it also has:

    • 4 USB ports
    • 40 GPIO pins
    • Full HDMI port
    • Ethernet port
    • Combined 3.5mm audio jack and composite video
    • Camera interface (CSI)
    • Display interface (DSI)
    • Micro SD card slot
    • VideoCore IV 3D graphics core
