You can get a SAS USB external enclosure but they’re in the $100 range, probably not worth it for 3TB.
For internal use, you can get a used PCIe SAS Host Bus Adapter fairly cheap BUT you need to do some research. Before you buy one you should confirm that there is a driver for the OS that you are using and that it is supported on your processor/socket/chipset. These cards are server hardware - many of them are not supported by Windows and/or are not compatible with consumer motherboards & CPUs.
Considering how the modding community made Skyrim a long-term success, this would be a very foolish decision.
