Check disk compatibility with RAID before purchase. WD drives did not work for me.

OK enclosure. Could not return after reading that Western Digital (non-enterprise edition) disks do not support RAID in ICY Dock manual. In my case I wanted to provide a reliable and small backup drive to operate in RAID 1 mode to store all of my precious personal files and photos. The problem with RAID is that if the enclosure controller fails in a low cost system you will probably not be able to get an exact replacement and both of your redundant RAID 1 copies will need to be wiped. Also, the enclosure latches really are not secure and the fan is noisy even when set to lower speeds. Overall, I would suggest consumers buy 2 backup drives with adequate capacity for their application. Run automatic backup and do a manual backup every 3 or 6 months on the second drive. This drive should be stored in a remote location from the main backup drive in case of fire, flood or other disaster. Drives like WD My Book get the job done without noisy fans and are a good value vs time and money to build your own RAID 1 disk.
