Nice NAS with the right functionalities

Have had the NAS for a week now and it works great. User-friendly interface with just the right amount of options. Great that there are many slots available and that a configuration can be chosen for a combination of different sizes of disks, so that old disks are still usable

Great NAS for home use with more than enough options. Both software and hardware. I am very satisfied with the purchase

Not cheap, especially considering the meager decoration. Additional parts are expensive
