Simple RAID 0,1 Enclosure with 2x 2TB Drives

I have had this unit for about 3 weeks. In my setup it is connected to my router to function as a NAS. When I first received the device, my computer would not recognize it. After re-seating the drives it worked. Not sure if this is due to a connector that is partially defective. Drives are not hot swappable. Mounting pins must also be moved from the old drive to the new one. When replacing a drive, the WD utility must be used to initiate a re-build. There is no advanced configuration of the RAID setup. You pick either RAID 0 or 1. There is no enclosure cooling and after some use the drives get very hot. Hot enough to burn skin. The drives do not seem readable outside of the WD enclosure (e.g. using a USB to SATA adapter). If the enclosure device fails, I'm uncertain if the data can be retrieved. Overall, I am content with the drive given the price.
