Is the connection speed 40gbps when connecting to thunderbolt 3 on a late 2018 macbook pro or 10gbps?

Inside this housing is a 2.5" laptop-style HDD, with a transfer rate of 135MB/s. Also, the interface is actually USB-C, which is "Thunderbolt 3-compatible" but is not Thunderbolt 3. What this means is that USB-C drives can be connected to Thunderbolt 3 ports and they work (as part of the TB3 spec). All of that said, the drive itself is the limiting factor in the transfer rate. Many manufactures like to put out the "5GB Transfer" funny business in their specs, but they are really only referring to what the port or cable is "capable" of, however the actual hard drive determines how fast it can read and write regardless of connection used. In fact, you will get the same performance out of this particular drive whether connecting to a USB 3.0, USB-C, or Thunderbolt 3 port as all are more than capable of handling the 135MB/s that the drive can put out.

My 2013 imac i7 connected to this drive with a usbc to thunderbolt cable doesn't see the drive. what's up?

It seems you are using the Apple Thunderbolt Adapter or similar, yes? Those will NOT work with this drive, since the port on the drive is NOT Thunderbolt 3. The interface is actually USB-C, which can be connected to/is compatible with a Thunderbolt 3 computer port, but does not work with a Thunderbolt converter since it's not an actual Thunderbolt 3 port. Any drive that says "USB-C (Thunderbolt 3-compatible)" is a USB-C drive.

Does this drive need A power cable?

No AC power needed, this drive is bus-powered by the USB cable to computer
