Choose the DS112+ if you need better performance: it has a 2.0 GHz Marvell CPU and 512 MB RAM versus the DS111’s 1.6 GHz CPU and 256 MB, though both have one drive bay with no expansion, no 10GbE, and no M.2 support. For basic single-disk file sharing, the DS111 is adequate; otherwise, the DS112+ is the stronger choice.
