Sadly, there is no adapter to allow you to use USB devices on the older Thunderbolt 2 ports your system has.
The adapter Apple offers is the other way around Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter so people who buy a newer system can use their older drives. I have not seen any other type of adapter and the system won’t have the needed logic to support the USB dialog via the TB port.
Think of it this way a water pipe can’t serve cooking gas as well can it.
I have a few of these Samsung drives which are quite good! It offers a proper USB A 3.0 interface, as such it will given you the full data rate the SSD can offer! I get Read speeds of 4.5 Gbit/s (560 MB/s) on 2012 & 2015 15” MacBook Pro’s
The theoretical transfer speed of USB 3.0 is 4.8 Gbit/s (600MB/s) vs. 480 Mbit/s (60MB/s) which is a 10X improvement.
Here’s a good review Samsung T5 SSD - speed test with 2013 Mac Pro (USB3.0) and MacBook Pro (USB3.1) Now keep in mind the max throughput of USB 3.0 I posted above and now just to the time point 5:30 to see the graph in the video. Do you see the max Read speed is just a bit over the max of the 3.0 spec so are you really gaining that much? Nope! The limitation of the SSD is holding back what the USB-C connection can offer.
So if you want still faster I/O then you need to look at a very different drive and sadly I/O channel as well which brings us to:
- Thunderbolt 3 (up to 40Gb/s)
- USB 4 (up to 40Gb/s)
A RAID’ed SSD drive to max out the full channel, as well as a newer Mac too!

Are you using the correct cable? USB2 and USB3 USB-A cables look alike but are different! There are additional contacts.
