The NiC needs a driver. I will try the Marvell/Acquantia 107 driver soon and may update here. This card in a PC would be a GEM. I am hoping that Synology will one day allow this to act as a 2nd NIC and 2nd NVMe cache pair. They sure don't want us using ANY NVMe for storage. :( **Q: Is the SSD on this card only used for network cache?** A: No - The SSD has no special relationship with the Ethernet interface, it's just a way to get two functions on one card. So you'll get the benefit of disk I/O caching regardless of whether that I/O is coming from the network or not. **Q: Why do we need additional m.2 adapter, sine the newer Synology comes with internal m.2 slots?** A: You might have an older model that would benefit from cache drives. **Q: Anyone using this on Ubuntu Linux?** A: I have used it on both Ubuntu 22.04 and Windows 10, and both work correctly with no manual driver downloads for install. Highly recommend if you want 10g and two m.2 slots for a limited pcie install. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 25Gbps speeds from your Synology NAS almost *by on Reviewed in the United States 29 January 2022* This SFP28 E25G21-F2 25Gbps card is finicky about which cable it gets plugged into the ports to work at 25Gbps. You must purchase one of the cables from the Synology compatibility list. If the cables are not from the compatibility list, it will only work at 10Gbps. We used the OEM Mellanox DAC cables which worked flawlessly. Amazon.com so-called Mellanox SFP28 cables don't work at 25Gbps (we tried 4 different sets).A switch with SFP28 25Gbps ports will be required to operate at 25Gbps. Your Workstations will also need SFP28 25Gbps network cards plugged into pcie 3.0 or 4.0 ports x8 to benefit from the 25Gbps network speed now available to your Workstations.Your NAS will need the fastest NVME drives installed in the cache slots in order to saturate the network bandwidth. One clause tho, pcie 3.0 NVME cache drives don't fully saturate the 25Gbps network. The Samsung 980 pro gen 4 drives do better than the gen 3 drives by a slight amount read, but notably better with write speeds. Even the gen 4 drives don't fully saturate the 25Gbps network installed in the NAS pcie 3.0 cache slots. Only if Synology would have installed pcie 4.0 nvme cache ports into the current NAS systems.Also trunk porting the NAS does nothing for speed, just redundancy. Must be a Synology thing?Our file access speed has more than double from our old 10Gbps network, now that all these hiccups have been ironed out of the Synology card. The changeover to this Synology 25Gbps network could have been easier with more technical literature from Synology.Hope this lesson of trial and error helps others purchasing this card to upgrade their NAS. ### ⭐ Supplied computer card with a broken factory seal. *by on Reviewed in Canada 29 March 2023* Supplied a card with a broken factory seal and tried to repair it under packing tape. ### ⭐⭐⭐⭐ Perfekte Kombination, aber saftiger Preis *by on Reviewed in Germany 15 May 2026* Wer seine Synology NAS fit für das moderne Netzwerk machen will, kommt an diesem Adapter kaum vorbei. Ich nutze die Karte in meiner DiskStation, um sowohl die Netzwerkgeschwindigkeit als auch die Performance durch SSD-Caching zu steigern – und das alles über einen einzigen PCIe-Slot!Installation & Kompatibilität:Der Einbau war gewohnt einfach: Karte in den Slot, zwei NVMe SSDs einsetzen, zuschrauben und fertig. Die Karte wurde von DSM sofort erkannt, Treiberinstallationen oder langes Konfigurieren waren nicht nötig. Typisch Synology: Plug & Play in Perfektion.Performance (10 GbE):Der Sprung von 1 Gbit auf 10 Gbit ist phänomenal. Beim Verschieben von großen Videodateien und Backups erreiche ich nun endlich die Geschwindigkeiten, die meine Festplatten im RAID-Verbund hergeben. Das Arbeiten direkt auf dem NAS (z. B. Videoschnitt) ist jetzt ohne merkliche Verzögerung möglich.M.2 NVMe Cache:Dass man zusätzlich zum 10GbE-Port noch zwei M.2-Slots für NVMe-SSDs bekommt, ist der eigentliche Clou. In meiner NAS waren alle Einschübe bereits mit HDDs belegt. Durch den Adapter konnte ich den Schreib-/Lesecache nachrüsten, ohne wertvolle Laufwerksschächte zu opfern. Die Reaktionszeiten von Docker-Containern und der Weboberfläche haben sich spürbar verbessert.Positiv:Platzsparend: 10GbE und 2x M.2 Slots belegen nur einen PCIe-Steckplatz.Verarbeitung: Massiver Kühlkörper sorgt für niedrige Temperaturen der SSDs und des Netzwerkchips.Zukunftssicher: Macht das NAS bereit für moderne Switche und schnellen Datenfluss.Stabil: Bisher keinerlei Verbindungsabbrüche oder Performance-Einbrüche.Negativ:Der Preis ist (wie bei Original-Synology-Zubehör üblich) im oberen Segment, aber die Stabilität und die Garantie, dass alles perfekt harmoniert, ist mir diesen Aufpreis wert.Fazit:Für Power-User und alle, die ihr NAS im professionellen Umfeld oder für große Mediatheken nutzen, ist dieser Adapter ein Pflichtkauf. Er löst das Problem des limitierten Platzes im Gehäuse elegant und liefert genau die Performance, die man erwartet.
