Do you have you a question about the Synology DiskStation DS218+ 2-Bay Desktop NAS Server with 4K Video Transcoding?

Q: This enclosure doesn't appear in WD's list of compatable NAS systems with their drives. Is their list incomplete or is it accurate? Many Thanks.

This NAS is the business and does what I expected of it (and a bit more). Running with 2 4Tb drives in mirror mode and doing all my Macrium Reflect backups to it. Also storing documents, video, music and photos. I then do backups to usb connected drives to provide an offline copy and also sync all documents, photos and music to MS Onedrive. Running plex to serve media files to my UHD LG TV without problems.

Synology NAS was very easy to set up once hdd's were inserted. Now it's running I don't need to think about it, It does it's job quietly and efficiently.

All looks good so far. Delivery quicker than expected from CCL. Quite complicated to set up correctly (resorted to buying a book to help!) but once working seems to be reliable in the short while Ive had it (1 month).

Brilliant device. It's a bit "techie" to set up and understand what's going on, but well worth the pain.

This product exceeds my expectations and needs. It is great device.
