Congrats on the purchase. Hopefully it meets your needs.
If the SSD seems a little small, I think you can grab yourself a reasonable sized SD card and leave it in the SD card reader full time for additional storage at a reasonable price (I think it has an SD card reader?). I think a lower class 64 or 128GB card should be less than $100. Otherwise, external drives are good too, but more in the way of being able to use an SD card.
