Q: Because it is mirrored Raid 1 does that mean only 2 TB usable space or is there two 4TB drives for a usable 4TB total?

A: So I can't see which product you asked the question on only that it's similar to the product I purchased. So If the unit has 2x2TB drives in RAID 1 you get just under 2 TB of usable space. If you configure them in RAID 0 you would get about 4 TB of space. So if the information says you have 2 TB of space in RAID 1 it means both drives are 2 TB and they are just mirroring. I hope that helps.

Q: Is this usable as home NAS or isn't it? One reviewer says no, but that seems to disagree with specs. Simply, can I set up share folder(s) for use by all the computers on my home windows network ? Is there restriction on type and number of shared files?

A: It is a NAS but shares are not allocated on a device basis but to users. You can map the volume on multiple network computers. Shares, unfortunately, cannot be size-limited and you can create folders but their content depends on user discipline.

Q: I’ve read in a couple of places that this device is ONLY usable when connected to the internet. Is it possible to use this on my local network only and disable access to the outside world?

A: Hi Wash, The My Cloud Home ships with a Gigabit Ethernet Interface. Best practice, to take advantage of the performance capabilities this device, is to directly connect to a Gigabit router or network switch with direct access to the Internet.
