## Description

Product description

Review: WOrks very good - I combined the 4 1Gb ports on my Synology 2419+ to get 4Gb throughout with an ubiquiti router. I have 12 10Tb disks in raid 5. The speed was a lousy 100Mb/s at best. Now I put this 10Gb X520-DA-1 card in the synology and connected it to an SFP+ port on my switch. Now I get a minimum and stable of 200Mb/s but I think thats the max of the disks combined. I'm very happy because an original card from Synology costs about 270€!!!!
Review: Scheda di Rete SFP+ 10Gbit - Compatibile e Affidabile - Ho acquistato questa scheda di rete SFP+ 10Gbit per il mio server Fujitsu Primergy con TrueNAS Scale e sono molto soddisfatto. L'installazione è stata semplice, con riconoscimento immediato del dispositivo. Collegandola a uno switch con cavo SFP+ DAC Twinax, ha funzionato senza problemi, permettendomi di sostituire efficacemente un LAGG di 4 porte. La qualità costruttiva è solida, e finora non ho riscontrato surriscaldamenti o malfunzionamenti. Consigliata per chi cerca una soluzione affidabile e facile da usare.
