With powerful CPUs and features for scalability and security, the two series of new Western Digital NAS (called My Cloud Expert Series and My Cloud Business Series) are designed with creative professionals and small business users in mind, and will arrive on the market this month.

The offerings cover a middle ground for WD, filling in a gap between the Sentinel series—geared for enterprise users and based on Windows Storage Server—and the My Cloud series for home users, which have both been on market for over a year. The price points will reflect that in-between space as well; the My Business Series will range between $1,100-$1,600 depending on whether the NAS is purchased equipped with 6 TB WD Red HDDs.

Note that both My Cloud Expert and My Cloud Business use custom Linux operating systems, and can replace a server facing Windows Server 2003 end of service, especially if that server is used in a file sharing capacity. The My Cloud Business Series has Active Directory support.

With My Cloud Expert and My Cloud Business, users get ramped-up CPU performance, as well as a clean UI experience that is compatible with Windows, OSX, Android, and iOS. The dashboard is accessible via Web browser or mobile app, and can sync with other cloud services including Dropbox, One Drive, and Google Drive.

The clean, minimalistic UI is shown below.
