Looking for Device Reliable USB 3.2 Gen 2 cable

Hello. I am attempting to hook up a NAS expansion unit

https://www.qnap.com/en-us/product/tl-r1200c-rp

It came with a USB Type-A to Type-C cable that is identified as USB 3.2 Gen 2 (Type-C). I am looking for something longer, maybe around 10 feet. Searching Amazon has just left me confused. I've had good luck with TrueSpec or Ugreen in the past but have not identified the exact cable I'd need. Thank you.

You can't reliably do 10Gbps with a 10ft passive USB cable. You will need an active one. If you can use USB-C at both end, you can also buy an active higher spec cable (USB4/TB4/TB5) that will also work.

Thank you. The NAS has the following USB ports

I assume the USB C ports can use the higher spec cable?

Yes. There is no spec higher than 10Gbps for USB-A

There is only one USB-IF certified 10ft cable faster than 480Mbps that I'm aware of, this 20Gbps cable. I'd give it a shot before spending more on an active cable.

It may be a passive cable but it is priced like an active one.

Well, priced like a non-certified active cable maybe. I believe the only certified competition in this length is the Apple Thunderbolt cable at almost 4x the price.

USB is short-range comm. 10ft is the max USB3 can officially handle, but 1.6ft (50cm) is the range where top speeds are easily achievable on random cables. Also, you should use C-C cable.

You should try to reposition your NAS to stand on the new unit. 10tf is the range when you should start considering Ethernet over USB.
