Hi Jason
Thanks for the great review of the WD MyCloud EX4. I had a similar type of system I purchased years ago called the LaCie 5Big. It had 5, 1.5TB hot swappable drives with auto backup, Raid, etc,. It worked great for years until it experienced it’s first power failure during a local storm. Upon power up it went through a rebuild mode which ended up corrupting all the data. After a very expensive data recovery I reloaded the unit, ran the system again and tested a simulated power outage. Same result. LaCie tech support had no solution other than to suggest a UPS and to do a controlled power down in the event of an outage. I did have a UPS connected but once it runs out in the middle of the night, unmanned, the resulting failure scenario remains.
I know you did a network failure test but did you happen to do a simulated power outage test on the WD EX4?
