I can't find it now, but I think I read that using both TB ports on the back will allow greater speeds. I searched this site for info, but haven't found anything.
The specs for the device say
- (1) Host Port - Thunderbolt 3 (USB-C) up to 40Gb/s (5000MB/s)
- (1) Thunderbolt 3 (USB-C) Port
Both ports look the same on the back, though. Is there a difference?

One is Thunderbolt, the other USB3, they share the same connectors. Thunderbolt is a superset of USB, and is faster. You cannot use a USB cable with Thunderbolt, either.

@softraid-support Which one is TB? I'm worried I'm using the wrong one. They look the same from the back. I'm using the one on the right, when looking from the back.

You bring up a good question, I do not know why they are labeled such, but the 2018 Mini has 4 Thunderbolt ports. Are you sure you are referencing a 2018 Mini?
Re: USB/Thunderbolt
Its so confusing!
USBC is a cable connection type. Its used for
USB 3.1 gen2
Thunderbolt 3 4 5
USB 4
Many chargers, also
Monitors/Display Port, etc.
The only way to tell the cable difference is by the logo on the connection point.
And some cables are active/passive, which you cannot tell by the cable, meaning some are faster for data, others are better optimized for video. Its insanity.

@softraid-support I'm talking about the ports on the back of the ThunderBay 4. The specs and your message imply they are different. If so, which one is the TB3 port?

they are both TB3. I will try to find out, but perhaps this relates to using a Monitor on one of the ports. I have never treated the ports differently (for drives), neither has any of the other engineers as far as I know.

@softraid-support Also please find out if I use both ports if that will offer a speed up.

No using both will not give a speed up, one will be ignored, as Thunderbolt does not support dual cabling.
If you have two fast devices, like our Thunderblades, each capable of 2800MB/s (Max of Thunderbolt 3), putting one on a different computer Thunderbolt bus will double potential throughput to 5600MB/s.
