Hello,
Connecting a Sata SSD to an USB 3.x adapter will not help you to speed up your data transfer if you think that.
The limiting factor here is the SATA interface. The maximum uncoded transfer rate is 600MB/s for SATA 3. Lower than the uncoded USB 3.0 640 MB/s, USB 3.1 (1280 MB/s) or 3.2(2560 MB/s)! The coded transfer rate is even lower due to flow control, packet framing and protocol overhead, (information that needs to be added to the data stream to let the drive and machine talk to each other). If two devices transfer data between each other it is always the slowest device that will define the speed.
Look at it this way: if I am riding my horse on a very small road and you are behind me driving a fast Porsche or Ferrari you will drive at the speed I am riding. Your speedy car will just be as slow as me on my horse!
So if it is your intention to connect the new drive permanently to your GTR 5 it is best to connect the SATA drive to your onboard SATA interface. In that way you don't loose your fast USB 3 ports. That would be a big waste!

Ps: I used the old names of USB 3.0,3.1 etc. Today there all named USB3.2. They messed the naming real up in 2017!
USB 3.0, is now called USB 3.2 Gen1.
USB 3.1, is now named USB 3.2 Gen2x1
USB 3.2, also named USB 3.2 Gen2x2, was released in 2017. It can be regarded as a USB 3.1 with dual channel mode. USB 3.2 use USB Type-C interface to enable dual-channel mode and each channel has a transmission speed of 10Gbps. Therefore, the theoretic speed of the USB 3.2 is 20Gbps.
But be careful :not every USB C connector is using the USB 3.2 GEN2x2 protocol! USB C is a connector form. You could have a USB C connector that uses the USB 2.0 protocol or one of 3.2x protocols.
Confusing no? Look at Wikipedia or google it for more info!
Now tell me: what protocol are those 3 USB 3 ports using on the GTR 5? And what protocol uses the USB C connector on the front? :-)
