The My Cloud EX4100 features four SATA drive bays that can accommodate 3.5" drives and use NASware technology. If users opt to use WD Red drives with this NAS, NASware technology helps to further optimize WD Red drives for the NAS environment in respect to factors such as vibration compensation, optimized power usage, and data protection in the case of a power loss or disruption. However, please note that this NAS does not include any drives, leaving users the freedom to install compatible drives of their choice.

This WD NAS also features AES 256-bit encryption that helps provide additional protection for your data, and RAID 0, 1, 5, 10, JBOD, and spanning can be used to configure various levels of data performance or redundancy. As this NAS features a built-in processor, this means that should a user wish to take advantage of the RAID functionality, the RAID controller is integrated into the NAS and thus RAID functionality will be controlled by the NAS and its hardware, instead of being controlled by software.

The My Cloud EX4100 operates on 100-240 VAC at 50-60 Hz and includes an Ethernet cable and a power cord. It is compatible with Windows 8.1, 8, 7, and Vista, as well as Mac OS X Yosemite, Mavericks, Mountain Lion, and Lion.
