Can I Connect a Late 2013 Mac Pro 6,1 To a Thunderbolt 3 Device?

I’d like to connect my late 2013 Mac Pro 6,1 to a Thunderbolt 3 device. I’m looking to add another drive, but I don’t want to buy one that won’t be the current type, as I’m looking to upgrade my Mac later this year. I’d wait, but I need the storage now.
Thanks in advance for your time answering my questons!
