Q. What cable(s)/adapter(s) is/are needed to connect a Crucial X8 500 GB SSD to a ThunderBolt (not 1,2 or 3) port on my iMac?

Q. What cable(s)/adapter(s) is/are needed to connect a Crucial X8 500 GB SSD to a ThunderBolt (not 1,2 or 3) port on my iMac?




I have a 21.5-inch, late 2013, 8 GB iMac that has two ThunderBolt ports and several USB-A ports.




The ThunderBolt ports are just plain ThunderBolt - not TB 1, TB 2, TB 3, etc.




The Crucial X8  SSD  promises speeds up to 1050 MB/s when connected to USB 3.2 Gen 2 Type-C port, which of course I don’t have.


 


The SSD as a Type-C USB port. It offers two ways to connect to the Mac:  Type-C USB -or- USB A.


  


It is my understanding that, if the iMac had ThunderBolt 3, I could use the provided Type-C to Type-C USB cable to connect the SSD to the iMac.




Which gets back to my question. Using different cable(s) and/or adapters, can I connect  the Type-C on the X8 to the ThunderBolt port on the iMac?

iMac 21.5″, macOS 10.15

2013 iMacs have Thunderbolt 1, which is compatible with Thunderbolt 2 devices.


Sadly Thunderbolt 1 and 2 are NOT compatible with USB 3.x so an adapter like Apple's Thunderbolt 3 to Thunderbolt 2 device will not allow you to connect your TB1 to an X8.


(The Thunderbolt 3 ports on newer iMacs are essentially bilingual: they can 'speak' as either Thunderbolt 3 or as USB 3 gen 2 and could connect to an X8.)

You can't use the Apple TB 3 to TB 2 adapter in reverse with that iMac and Crucial Drive, because that USB-C Crucial Drive does not have it's own power supply.

Your best bet, is to just connect that Crucial drive up to one of your 2013 iMac's USB 3 ports using the USB-C to USB adapter and live with 580 to 600 MB/s.
