    Perfect, but I don't ask too much of him

    I use this NAS to store a few holiday movies and hold a virtual machine (win10) to retrieve them from my friends. It does its job perfectly. I never run out of power on the VM. Installation is easy.
    The fans can be noisy but are exchangeable if they really bother you. It does kick in from time to time, especially when I'm transferring large files or playing a rather large movie on my APPLE TV. Otherwise it's dead quiet, you can only hear the discs.
    The SYNOLOGY interface is rather sleek and guides you in your actions with a lot of advice in the interface.
    It is not far from perfection for my case of use. You have to pay the price...
    I've been using it for a while now, but it's a great service and I'm very pleased with the service. I've been to the store for a while now and it's been a great experience for me.

    Excellent NAS

    I've had it on endurance test 24/7 for over a month now. Everything runs perfectly well, barely noticeable noise level.

    I bought this DS1621+ to replace my Linux server which is a bit old.
    I'm a bit reluctant at first, so I set up an endurance test plan before transferring my data to it.

    I increased the memory to 16GB (with 2 Kingston ValueRAM SO-DIMM 16GB DDR4 2666 MHz CL19 DR X8 SDRAM arrays). The NAS displays a warning, but everything works.

    I'm not sure if it's a good one or not, but I'm sure it's a good one.

    I'm going to be able to transfer my data and evaluate the caches now.
    I'm going to add an inverter to it. :)

    Excellent

    Perfect LDLC service and speed, as usual.

    Switching from a too slow DS414j to this DS1621+, it's night and day, a racing beast that makes me rediscover Synology's DSM OS, and real performance.
    It's a pleasure to manage your NAS in BTRFS, to play with virtual machines, to explore the possibilities with a real server.
    In short: a very nice toy - Thanks Synology (and LDLC!)
