Are there any decent options out there for a USB C Thunderbolt external SSD? Such as for a working drive. I can't afford the new fancy LacIe drives.
I recommend this approach as well. Grab a respected USB-3 enclosure and low cost SSD drive and put together your own accessory. You don't need a Thunderbolt enclosure, a USB-3 (using USB-C connector) will suffice. TB is overkill for the transfer rate of single SATA and PCIe SSDs unless you need the daisy chain capability of TB peripherals.
What enclosure did you put it in? If your enclosure has a USB-3 port (e.g. a USB-3 micro B or type B) then you have no worries about a bottleneck. There's no need to get a USB-C enclosure where the only difference would the connector if USB-3 is the protocol.Thanks! I ended up purchasing a Samsung 250gb m.2 as a working drive to put in my new enclosure. However, If I could ever find a usb-C case to put it in, I may make it portable. Would USB-C Bottleneck the speed of the m.2?

I think you're spot on. USB3 gen 2 theoretically supports up to 10 Gbps (gigabits/s) and the new m.2 PCIe SSDs can do 2500MB/s (megabytes/s) == 20 Gbps so USB 3 gen 2 would be a bottleneck at maximum theoretical transfer speeds.If you purchased a m.2 PCIe SSD like the Samsung 960 Evo or 960 Pro...
USB will be a huge bottleneck, regardless of the version - The Samsung 960 Pro can read up to something like 3,500 MB/s and write something like 2,500 MB/s. So you would need ThunderBolt3 to take full advantage of the 960 Pro (along with an expensive enclosure) or ThunderBolt 2 (which would still not quite max the SSD.)
