If something is corrupt with the on-board controller it writes junk to both drives. If I have a different controller for each SSD, aren't the probabilities better that I have a good drive?
I was running RAID 5, 3 HDD config. A drive went bad and the software was unable to recover my data. This was data I access once in awhile from my previous business, but still want access to. Then shortly after the Windows 10 Upgrade on a single WD 1TB HDD, the system crashed and could not find any of my system recovery files. So I purchased my first Crucial MX300 1TB SSD. Everything was great. Used Windows File History to the old WD 1TB HHD.
Then one day I woke up to the computer constantly booting into Windows long enough to see the Windows logo, then reboot, repeat, repeat, repeat... Must have been doing it all night. No pressing of function keys at Windows start-up mattered.
That brings us now. Sorry for such a long story. But, if a separate controller writing to its own disk, if there was a motherboard controller problem, wouldn't I end up with a good disk from the separate controller? Or is this flawed thinking? It's okay, I'm open to discussion, that's what forums are all about?
