    Good price for this model as you highlighted but the only difference between this and TS-431P is the upgradable RAM (and the ridiculous price difference between the two) from my reading. I presume additional RAM isnt going to assist too much in trying to get the machine to do any form of transcoding for plex.

      In addition, TS-431P2 comes with quad-core processor, while TS-431P comes with dual-core processor.


    quick search on reviews turns up this is a pretty decent unit.


    So it's not suited to transcoding for plex? Sorry, im a bit of a novice on this stuff.


    Does this unit have flex-raid (or the QNAP equivalent) ? IE can you mix disk sizes in raid5 (equivalent) without losing capacity?
    (eg. 6tb+6tb+4tb+4tb = 14tb usable, not 12tb).

      (eg. 6tb+6tb+4tb+4tb = 14tb usable, not 12tb).

      wouldn't that be 20tb ???

        He did say Raid5…..

        Not if it's redundant, no. Synology and Readynas (and presumably others) have features which mean you can mismatch disk size and use the largest disk for parity (so 6+4+4 and a 6 for parity = 14). I'm asking if this does the equivalent, without formatting the 6tb's down to 4tb to make all drive sizes a uniform 4tb.

          I don't think the QNAP will do it. Not at this level at least. I haven't seen anything to imply that it will so far.


      Is it possible to use all 4 bays for max storage without using any protection etc.?
      e.g. 8TB, 6TB, 6TB and 4TB .. can I have total of 24TB?

      And different CPU


        Just noticed that in the comments - thanks
        CPUs from the spreadsheet linked above.

        TS-431P ARMv7 (Alpine AL-212) 1.7GHz - (Dual Core)
        TS-431P2 ARMv7 (Alpine AL-314) 1.7GHz - (Quad Core)

        Neither of the above are suited for transcoding in Plex however

    As long as you ahve decent upload speed you can pretty much turn off transcoding for most videos - just tell it to use the maximum and original quality


      I am curious if it can be turned off…
      I am under impression there is no way to switch it off.


        If you play at maximum (with original box ticked) quality it will only transcode weird formats that it doesn't natively support, so as long as your library is full of the usual mp4 x264 videos no transcoding is needed.


    Just bought this to replace my QNAP TS-431P, as well as a NAS I use it as a docker host running tvheadend, unifi-controller, home-assistant, calibre-web and portainer. It's been really stable despite only having two cores and 1GB.

    Forget transcoding, just use Kodi to access the files.

    Now I want the 8GB RAM upgrade, this is what QNAP specify:

    DDR type: DDRⅢ(204 PIN)
    Capacity: 8GB
    Spec: SAMSUNG 512M X 8
    Manufacturer: TRANSCEND
    Frequency: 1600
    Form(PIN): 204PIN
    Manufacturer P/N: TS1GSK64V6H SAMSUNG
    Power Supply: 1.5V

    Anyone know a cheap local equivalent?


      Going from TS-431P to TS-431P2 was the easiest upgrade ever, just moved the disks and it all worked. Pulled an 8GB SODIMM from a laptop and that worked fine too. Now what will I do with a TS-431P I don't need…..


    Is this better value with 4Gb ram for $356.15?

    Or better to get with 1g and after that upgrade to 4G?



      If you're comfortable with DIY, you can get a 4GB SODIMM RAM for around $30.


        How well does this run with 1gb if I don't plan on running any apps on it? Will I benefit from upgrading the ram? Does extra ram affect things like raid5 performance and/or rebuild speed?

        Thanks for answering all these questions.

        • +1 vote

          IMO, if you don't intend to run additional apps, 1GB RAM should be fine. Since the 1GbE network is the critical path, the improvement of the additonal RAM on performance improvement is marginal. And I don't think RAID5 operation/rebuild is memory bound.


    Does anyone know if this model requires you to do the 3.3v tape trick for a shucked drive or not? I read some NASes do, some don't.

    I have 4 x 8gb drives ordered to fill this baby, and need to know if I need to buy some Kapton tape…

    Thanks in advance.
