I know the price tag is a bit steep but it really is worth the investment. I love this thing and will be adding faster/bigger drives in the near future. Once the M2 drives come down in price a little bit, I will be adding two of those as well.
I am the owner of a small business, we develop computer software for medical applications and reliability of our backup systems is of utmost importance to our company. I would not recommend buying any unit from Synology (as the software is the same across units) to anyone for business or personal use.
- SNAPSHOTS: Synology advertises the capability of taking snapshots of a shared folder contents, usually these snapshots would be taken, for example, hourly so that if users mistakenly delete or alter a file in a non-desired way they can recover them. Snapshots would integrate with the time machine on mac and with the "previous versions" mechanism under windows. THIS does not work if you encrypt the shares, but the company does not mention it in the product features description. What business (or private owner) would nowadays not encrypt the contents of their systems? so basically this renders this functionality useless.
- DROPBOX BUSINESS SYNC: Synology advertises syncing with Dropbox business. What's the difference between normal Dropbox and Dropbox for business? The primary characteristic is that in Dropbox for business you have team folders that are shared across the company users. We were highly interested in this feature, but when you setup the synchronization task the team folders do not show up on the Synology administration software. After speaking with support I have discovered that syncing of team folders is not supported .... what does it mean then "support for Dropbox for business????"
- NORMAL DROPBOX SYNC: it is common nowadays to build "hybrid clouds" where the NAS provides network shares to the users that are physically on the NAS network and 3rd party could services (Dropbox, Google Drive etc) are used to provide shared folders to users on the go. The NAS synchronizes its contents to the could contents. This is a functionality highly advertised by Synology, but the syncing seems to go on for ever and ever (days) also on folders that have been setup as a test and which nobody touched.
Other problems exist in general with the software. For example: I have created a volume where to keep the data and one volume to use as a target for backups, and I have encrypted both volumes. Whenever I setup a backup task the backup application asks me "are you sure you want to backup an encrypted folder to a non encrypted folder?" .. really ? I have just encrypted both ....
Other similar problems exists. In summary some key features are not as advertised, missing or not working, and the confidence of entrusting this machine with protecting critical company data has vanished. I am returning the product.
What is really disappointing is that, if you read user forums, also QNAP (the other well know producer of NAS systems) does seam to have similar issues with their could syncing software. At least snapshots on encrypted shares are apparently supported by QNAP.
The only positive note that I can express is that support was quick to respond to my support requests.

Die 1515+ hat nach 18 Monaten den Geist aufgegeben und lies sich nicht mehr einschalten.
In den Foren taucht der Fehler häufiger auf im Zusammenhang mit dem Prozessor des Intel C2538.
Nach Rücksprache mit der Synology Hotline ist ein Prozessorfehler der von Intel zugekauft wird als Ursache verantwortlich. Na Ja das lassen wir mal so stehen.
Bedienbarkeit, Geschwindigkeit, .Sehr gut mit Synology.
Mit der 1515+ war ich zufrieden.
Die 1517+ habe ich dann gleich mit 8GB Arbeitsspeicher bestellt, was sich auch in der besseren Geschwindigkeit wiederspiegelt.
Die Migration der alten in der 1515+ verbauten Festplatten war völlig problemlos.
Alte Festplatten in das neue System eingebaut über den WEB Browser das System angesprochen.
Das System erkennt die vorhandenen Festplatten mit der vorherigen Einstellung und frägt ob man dies übernehmen möchte. Auf Migration bzw. mit „JA“ bestätigen und das System läuft nach 10 Minuten wieder tadellos.
Noch die USV angeschossen an das Synology System. Klappte auch auf Anhieb.
Lob an die Entwickler zum System und zur Softwareoberfäche.
Hatte bis vor knapp 3 Jahren ein Seagate System. Davon kann ich wirklich abraten.
