The reason I like SSDs is there's nothing to break. Hard drives fail sooner or later and for backup, SSD is great, albeit more expensive. In my laptop, I have 2 SSDs and one HDD. I store all my critical stuff on the SSDs and the data on the HHD is backed up to the cloud.
Also, Thunderbolt3 uses a USB-C connection and is essentially DP (display port) and USB-3.1 combined. You should be able to connect a USB-C drive to the Dell. I recommend the Samsun 850EVO SSD drives.
I have 500GB SSDs in several computers, but I also have HDDs for programs and data.
