SSD vs. 7200RPM Drive Tests
 
So I was curious... what would the BlackMagic Disk Speed Test show if I ran it on a 7200RPM Lacie D2 Thunderbolt 2 external (4TB) vs. a Samsung EVO 860 (2TB) SSD with USB 3.0 external dock vs. a Samsung EVO 860 (2TB) SSD with a Thunderbolt 2 external dock?

Mac Pro 2013 3.5GHz 6-core Intel Xeon E5 / 32GB RAM / High Sierra

Results below :D

Lacie 7200RPM D2 TB 2 external: Write: 192 MB/s -- Read: 196 MB/s
Samsung EVO 860 SSD USB 3.0 external: Write: 252 MB/s -- Read: 266 MB/s
Samsung EVO 860 SSD TB 2 external: Write: 336 MB/s -- Read: 383 MB/s

Thought others might find this interesting...

Now check your Samsung usb test straight into the USB3.1gen2 ports found on the computer vs the USB3.0 or Usb 3.1gen1 port found on the dock.

I think the 2013 Mac Pro is only usb 3.0 not 3.1 (correct me if I am wrong).

According to everymac.com no 2013 Mac Pro has USB 3.1 ports but plain vanilla USB3 ports. Same for the new cheesegraters. Now one can put cards with USB 3.1 ports on them in the original cheesegraters.

To be technical: All USB 3.0 ports are USB 3.1 ports. They rebranded them to USB 3.1gen1 (or just USB 3.1).
The newer USB 3.1 ports (10Gbps) are USB 3.1gen2.
The USB trade group is a tricky one.

And the new Mac Pro (coming soon!) has USB 3.1gen2. If you look at everymac it or click on the USB line, it says
Quote:

USB Ports: 2 (3.0), 4 (C)*
That "4 (C)" is 4 type C ports and all type C ports are 3.1gen2 (in this case dual use Thunderbolt3 and USB 3.1gen2.) That is explained when clicked.

All USB 3.0 ports are NOT USB 3.1 ports. While physically they may be the same connector the theoretical throughput speeds are different. USB 3.0 has 5 Gbps and 3.1 ports are double that at 10 Gbps. And not all type C ports are USB 3.1gen2. From this page: https://www.howtogeek.com/211843/usb...youll-want-it/
there's this little bit of data:
USB-C, USB 3.1, and Transfer Rates

USB 3.1 is a new USB standard. USB 3‘s theoretical bandwidth is 5 Gbps, while USB 3.1’s is 10 Gbps. That’s double the bandwidth—as fast as a first-generation Thunderbolt connector.
USB Type-C isn’t the same thing as USB 3.1, though. USB Type-C is just a connector shape, and the underlying technology could just be USB 2 or USB 3.0. In fact, Nokia’s N1 Android tablet uses a USB Type-C connector, but underneath it’s all USB 2.0—not even USB 3.0. However, these technologies are closely related. When buying devices, you’ll just need to keep your eye on the details and make sure you’re buying devices (and cables) that support USB 3.1.

They are. The USB Promoter Group rebranded as I stated before. All USB3.0 are USB3.1 gen1 now. It happened in 2013. And, yes, USB3.1 gen 1 is 5Gbps. And USB3.1 gen 2 is 10Gbps.

That is not what I said. I said on the new Mac Pro it is. As is explained on everymac. The Thunderbolt3 ports are dual use to USB3.1gen2.

From everymac under details:
Quote:

*By default, this Mac Pro has two USB 3 ports (USB-A up to 5 Gb/s) and four Thunderbolt 3 ports (support for Thunderbolt 3 up to 40 Gb/s and USB-C up to 10 Gb/s as well as DisplayPort). Two of the Thunderbolt 3 ports are provided by a pre-installed Apple I/O card and two are on the top of the tower case. Other connectivity can be added via PCIe cards.
