VALUE FOR MONEY
designIt's a budget/Cost Effective NAS and therefore you cannot expect a superior build quality as you see in the QNAP TVS-1282T or the Synology DS3617xs. But even though it is a bit plastic-y, it is still functional and keeps the noise lower than you would expect.
featuresThe Annapurna CPU, though not breathtakingly powerful is still more than able to perform many, many tasks and is actually alot better than the CPU in most Budget or Cheap NAS servers
performanceIf you need a small to medium task level NAS for your file server needs and light to Medium Media Access via DLNA or the Native QNAP Apps, then this NAS will perform very well for you indeed
valueExcellent Value and if you need a RAID enabled NAS server for Windows or Mac - The TS-431p is the NAS device for you.
designThe Plastoc trays and horrible lockless design make you feel like you are breaking the trays each time you use them. I would recommend replacing the trays with Metal Trays from QNAP
featuresNevertheless, it is still an ARM CPU and therefore functions and applications like PLEX Transcoding and Virtual Machines are not available to you with a NAS like this one.
performanceHowever if you need slightly more intensive, larger file operations or who to move towards that in the next year or two, then you are better off spending a little more on the QNAP TS-453A here - https://www.span.com/product/Qnap-Desktop-NAS-TS-453A-4G-4-Bay-RAID-0-1-5-6-4GB-RAM-~52841
valueIf you want a NAS that can do more intensive operations then what you save in the low price, you also lose in it's ability - this NAS is excellent for the price if you need smaller file access/volumne - Not if you want RAW power.
