Overview
Slotting into a desktop or server, this TP-Link card turns a PCI Express slot into a ten gigabit Ethernet port. It negotiates down through the slower speeds automatically and ships with a CAT6A cable.
Ten gigabit speed and the included cable are the reason to buy it for a fast connection to a NAS or server. The limit is that the rest of the network must also run at that speed.
Who it's for
Editors, developers and home lab users who move large files across a local network will use the speed. Users on a standard network gain nothing from the faster port, and laptop owners need an external adapter.
Pros and cons
- Ten gigabit speed
- Negotiates slower speeds automatically
- CAT6A cable included
- Wide Windows and Linux support
- Needs a free PCIe slot
- Needs matching network gear
- Low profile bracket not listed
Performance notes
The port auto-negotiates with the switch, so it falls back to slower speeds on older gear. Reaching the top rate requires switch ports and cabling at that level. QoS prioritizes traffic to reduce congestion for games.
