There are a large number of SSD options for the T430 ranging from 200GB to nearly 4TB. There are both SATA and SAS options, as well as options for mixed use or read intensive drives. If you can share more details about what you're looking for, I'd be happy to assist.
There are a few 1.92TB options, but then they jump up to 3.84. You would be better served by contacting sales when it comes to pricing, since they have better information than I do. Hopefully, these part numbers help you pick out a good option.
Here are the SKUs for all of the SSDs close to that 2TB mark:
