    Magnets got a reaction from manuti in Upgrade from Orange pi PC?   
    That looks neat and essentially gives me 3 USB ports as I would be using USB-SATA adapter anyway but it's $55 USD including shipping to the UK
     
     
    sound good

    Magnets got a reaction from manuti in Upgrade from Orange pi PC?   
    I have an orange pi PC that I use as a simple NAS (NFS, smb, iscsi) and for openVPN occasionally but want something new with GbE.
     
    What is the best upgrade that will give me 2 or more usb ports, GbE and a faster processor? With decent software support ()? I don't need HDMI or wifi but it would be a plus
    512MB-1GB RAM
     
    opi zero plus?
    opi PC 2?
     
    Around $20 shipped ideally

    Magnets reacted to yam1 in Recommended SBC below 20USD range.   
    Here are some of my SBCs that are under $20 (see photo below).  I have divided them into two categories, with hdmi and not. The ones on the left are without, and on the right are with. The ones without are mostly orangepi's and nanopi's. Just do a search on their web sites and if it is under $20, I have it. One thing to consider is the ones with two spi channels (e.g. nanopi core 1 - note core 2 is better but its over $20), this would allow connecting two spi screens. If you connect two relatively big 3.2 ili9341 screens, with the browser stretched across them, your experience would still suffer but it would be okay in some extreme situations. The ones with hdmi include, raspberrypi zero w (double spi), nanopi A64 (double spi), pcduino4 nano (double spi), nanopi m1 - same as pcduino4 nano (double spi), and the other three orangepi's. Bananapi zero is slightly over $20, I have it connected to a lap dock. Of these, the best is pcduino4 nano (get it on ebay between $5 to $16), supported well in software (armbian), and nanopi a64 ($19.99?) is my second choice, software support is getting there (may be?), at least double spi works with pine64 image (latest kernel). Raspberrypi Zero W is only $5 from my local store, and dual spi screen with camera works, you really can't beat it in price.

    My samsung evo 64gb went read-only recently (20 months old) and then would not boot. I copied to another card and ran fsck and all seems OK. I think the later evos were not as well made as the earlier batches.

    On the ultra low end you can get a pogoplug v4, and if you get the pink version it has 2xUSB 3.0, 1xUSB2, SD slot, gigabit ethernet and a sata slot. They also come with a 12v/2A power supply and you don't have to buy a case. They have pretty crappy performance compared to the newer boards and do run hot.

    I doubt you will get much improved performance because SW decode h265 will be very slow
     
    I think a raspberry pi is better for video because the openmax platform has more support and allows hw decode too.
