I had to look this one up.
We are both right.
UHS1 will default to Class 10 speeds with a device that does not support UHS1. Thus Class 10 is kind of like a minimum. Also, this particular product
appears to have 10MB/s writes and 40MB/s reads. This is in comparison to a Class 10 device
from the same manufacturer, which has the same 10MB/s writes, but only 20MB/s reads. Thus, it is faster in one spec, but the same in another. I've also noticed that some manufacturers market their products as both Class 10 and UHS1. I guess it is like saying that a HDD is SATA 6GB/s versus the same drive with SATA 3GB/s. Both perform the same, but one is capable of faster transfers if the media supports it.
This particular Team device is kind of disappointing for the slow write speeds, but the read speeds should butt up against the limitations of USB 2.0 when transferring data in an adapter.
There are other UHS1 products
which cost much more but are without a doubt much faster. The product I linked has 90MB/s writes!!!
Still, $21.59 isn't bad for a product with minimum
Class 10 performance, as it is the same price as most sales of 32GB Class 10 chips.
The bundled USB card reader is a nice touch, though disappointing that it isn't USB 3.0.
