The My Cloud lineup from WD has evolved over the years, starting with personal storage in the My Cloud home and Mirror to the power user platform in My Cloud Expert EX2 and EX4100. The highest end of this portfolio includes two models, the PR2100 and PR4100 with each having several capacity options.


Turn-Key platforms are gaining popularity for both home and small businesses as the potential cost savings of building your own has dwindled over the years thanks to new technology.

The internal drives are 10TB WD Red units, model number WD100EFAX.
