    Excellent impression

    To replace a Nas Synology DS212+ that had become slow, and taking advantage of a promotion
    I jumped at the chance, knowing that I was looking at QNAP for the Multi-Gigabit Ethernet ports.
    The migration from the DS212+ worked, but not perfectly, the multimedia services were no longer functional.
    So complete installation from scratch in RAID5 with 4 x 3TB WD Red drives.
    DSM 7 is a good surprise with new packages Active Backup, Docker, Virtual Machine Manager.
    The DS420+ is responsive, it's really a pleasure. Yes, I have pumped it up to the max: Added 4GB of ram and 2 Samsung 500GB NVMe SSDs.
    For the Multi-Gig Ethernet, as indicated in the questions section I installed a driver available on GitHub which works very well, with an ASUS 2.5Gb card in USB 3. File copies are now done at 280 mo/s. PC backups are fast with Active Backup.
    I finally find the pleasure to use my Nas.

    A little luxury doesn't hurt

    With the release of dsm7 and the removal of some packages, I decided to upgrade to a higher model. It's a real pleasure to be able to use docker and VMs (well, you have to add some ram to be safe).

    Very satisfied

    Excellent product, at least as fast as the DS1815+ that it replaces in my home.
    The change of NAS is done almost automatically with all the data recovered.

    Easy migration from a 2013 model...

    Synology NAS are well known and well known.
    I just upgraded from a DS413j to a DS420+. The doc said: impossible migration between these models.
    I reset the DS413j as instructed, moved the disks, started the DS420+, installed the system (in fact, I accepted that everything was done). The data, on the transported disks, was present. (although migration was impossible!!).
    If the migration had been possible, I would not have had to (let) reinstall the system. In both cases, the data was preserved.
