I'm upgrading my network to 10GB, so I order a 10GB SFP+ card for my Synology Enterprise NAS. With this SFP+ cable I connected it to the NAS and my Microtik 10Gb switch. Bam, 10GB of speed from a six year old NAS. (Maybe it's 6 years old, but it has a 2.7GHz Xeon processor, 32GB RAM and 12 x 10TB SAS drives. I'd say it's worth upgrading. Previously the NAS had 4 1GB network connections.
