“The overview storage capacity states 12TB, but specifications describe each hard drive (in a duo-hard drive system) as 6TB in a RAID1 configuration, which yields only 6TB storage capacity. What is the true storage capacity of this unit?”

The unit contains 2 6TB drives. When you access it from your computer you only see 6TB. Internally the unit takes everything you write to the 6TB and "mirrors" it to the second drive. That is the way RAID1 works. This way if either drive fails, you have a copy.

Hi, Please know the My Cloud Home Duo is configured in RAID1 by default. To use the full capacity of 12 TB, you may change the device configuration to Full Capacity Mode(JBOD).
