    Synology DiskStation DS420j

    Good hardware. Procedures for transferring disks from one station to another far too complex and rather poorly explained. Some of the software included in DSM 7.1 lacks flexibility and is not configurable enough.

    Good product and advice

    Easy installation and start-up as a replacement for a DS216J NAS: its network interface, hit by the storm, fizzled. I added gigabit surge protectors on my network links.

    No worries

    Mounted to complement a DS213J, which is starting to fill up, this NAS installs in less than 1 hour....The DSM 7.0 version of this model is much simpler and more intuitive than the previous ones, more flexibility in creating shares.
    The most time consuming part was the migration of 3.8TB of files to the raid. For the moment, only 2 HDD 8TB installed, the 3rd to follow very quickly for 16TB of storage in raid SHR.
    Received Thursday afternoon, 100% operational by Saturday morning, very happy with this new equipment. If the reliability is the same as the first one, this DS420J will be with me for years....specially since there will be a slot available to reach 24To.....
