It all really depends on how patient you are too. I have an UltraPAK on an external USB 2.0 drive (NOT the USB 3 drives we ship out, but the old ones) and speed doesn't bother me. Bootup of BIAB is around 10 seconds - sure, that would be faster if I stuck it on my internal SSD, but I'm not gonna lose sleep over it.

If you're using BIAB professionally and need the absolute highest speed, then a bigger internal SSD would do it - they're not hugely expensive these days.
