My Windows PC locked up again at the weekend. Followed by another 12+ hour RAID rebuild. So I’m done with it.
I waited for the rebuild, split the mirror, then installed SyncToy, some little Microsoft program that will automatically sync directories, like rsync on Linux, but with a GUI. It has to be run manually (or scheduled to run periodically in the background), but it seems far more robust than Windows RAID. And, even if one disk dies, at least I have a recent backup on the second, rather than an unreadable broken RAID.
I’m just appalled to see that a bloated multi-billion-dollar corporation can’t even get something as simple as RAID mirroring to work competently.
