From the manufacturer

Synology 25 Plus Series NAS ranging from 2 to 8 bay, scalable to 18 bay epansion units (DX525)

Extra speed when you need it

What's different?

Synology DS425+ is a solid 4-bay NAS that's perfect for home offices, small businesses and content creators who need reliable storage without the complexity of enterprise systems. The standout feature is its 2.5GbE networking

  • Enable remote access to your files or keep everything local and offline
  • Improve efficiency by adding SNV3000 or SNV5000 series M.2 SSDs without sacrificing a drive bay

    Synology has always been rock solid. I moved from DS413 to this one completely uneventfully.
    Since my use is primarily at home, the NAS is way more complicated to configure than a simple backup. However, there are lots of help files and for the most part warnings make it difficult to make a catastrophic mistake. My last NAS lasted 12 plus years and was no longer getting updates.
    Drive arrived in about 48 hours and was well packaged. Having to wait for delivery and sign for it is a bit of a pain.

    1.0 out of 5 stars Synology startet den Closed Shop - v?llig unakzeptabel und sehr schade
    Reviewed in Germany on September 15, 2025
    Verified Purchase
    Bisher habe ich alle Server von 4-bay bis 8-bay bei Synology gekauft - guter Support, gute Technik, relativ einfache Handhabung.
    Ein Server (DS420Plus) hatte nun Probleme und bevor ich irgendwelche Datenverluste riskiere, tausche ich lieber den NAS-Server aus.

    Interessant war f¨¹r mich die neue Generation DS425Plus, da dieser Server endlich mal einen 2,5 GB-Port hat.
    Auf Nachfrage beim Support hie?t es, dass eine Migration der HDDs problemlos m?glich ist, auch wenn die Festplatten nicht in der Kompatibilit?tsliste von Synology stehen. Ich setze Helium gef¨¹llte Festplatten ein (Toshiba NAS300 12TB), also genau auf NAS-Betrieb optimierte, gute HDDs.

    Die Migration funktioniert einwandfrei, auch wenn ich danach alle Synchronisations-Jobs zu anderen Servern neu aufsetzen muss.
    Dann sehe ich die Information des DS425Plus-NAS, dass die eingebauten Festplatten sofort gegen Festplatten in der Kompatibilit?tsliste ausgetauscht werden m¨¹ssten. Soll ich jetzt mehrere einwandfrei funktionierende NAS-Festplatte entsorgen, nur weil Synology die Firmenpolitik ?ndert?
    Zus?tzlich die Anzeige, dass die in der DS420Plus vorher installierten Cache-Speichermodule von Crucial in der DS425Plus nicht akzeptiert werden ¨C also auch in den M¨¹ll m¨¹ssen nach Ansicht von Synology..

    Ein Blick in die Kompatibilit?tsliste von Synology zeigt, dass nur noch Komponenten von Synology selbst (Festplatten und Cache-Speicher) von ihren neuen NAS-Servern akzeptiert werden.

    Nat¨¹rlich kann Synology versuchen, f¨¹r ihre Ger?te einen "Closed-Shop" einzurichten und nichts mehr zuzulassen, wo nicht Synology draufsteht. Ob sie damit Kunden behalten werden, wage ich stark zu bezweifeln. Ich lasse mich jedenfalls von niemanden in einen Closed-Shop zwingen und die n?chsten NAS-Server werden daher ganz sicher nicht von Synology sein. Es gibt vergleichbar gute Produzenten von NAS-Servern (wie QNAP), die noch ein ungest?rtes Kunden-Lieferanten-Verh?ltnis haben.

    Vorl?ufig setze ich nun noch eine nachgekaufte DS420Plus ein, um sicherzustellen, dass nicht nach einer Wartefrist nach der Migration meine Festplatten von Synology einfach abgeschaltet werden.

    Echt schade - Synology stellt richtig gute Produkte her - aber so geht man nicht mit Kunden um!
