### ⭐⭐⭐⭐⭐ You need this!

### ⭐⭐⭐⭐⭐ Great to connect Qnap to workstation
*by B***L on March 19, 2026*

Worked to connect network card in Threadripper workstation to Qnap NAS. No connection issues, has been solid for several months now. Be aware the the nature of the connector it does stick out a bit and the cable itself is a bit on the firm side so its not going to be able to bend sharply.
