If configured as RAID1, can I keep it connected to my pc via usb and actively write files to it--? Essentially, using it as an external storage--?

Yes this is basically how we use it, but its connected to a server and used for daily backups.

Can 2 drives be accessed separately, i.e. as a dual drive docking station or do you have to setup a RAID configuration?

The TR-002 can also be utilized as a DAS (Direct-attached Storage) device, allowing you to directly access its content just by connecting it via USB.

Can this unit serve as an external storage device?

Yes, this unit can serve as an external storage device by utilizing its DAS (Direct-attached Storage) functionality, allowing direct access to its content via USB.

I want to pull my drives out of my "WD Cloud EX2 Ultra" and use them in this enclosure so I can use them as external storage and not deal with the limitations of the NAS enclosure. Anyone with experience with this?

I have an older version of WD cloud and basically did this. You just pull the drives out remove the mounting screws, add the new screws for the QNAP, stick it in, reformat and set the raid you want and your done.

Hello My Friend; If configured as RAID1 with two 8TB drives are installed, is my storage capacity 4TB or 8TB--?

8TB. RAID 1 is a mirroring configuration.
