Choose the DS109 if you want a clearly faster, more capable box: it has a 1-bay design too, but with a stronger CPU and more RAM headroom than the DS108J. Neither model offers 10GbE, M.2, or any bay expansion, so the real decision is simply older/lower-end DS108J versus the better-performing DS109 for basic home/SMB file storage.
