Slowly ;-). I had an old laptop with HDD, and it was seriously painfull.

One solution could be to mount your SSD as a cache for the bigger HDD.
I know it is possible, but never tried it myself.

Another solution is to use a different store path for your experiments.
If you still want binary cache support, i experienced very good results
with proot.
