I recently have had such failures as well (as mentioned on my site), but if my mantra is followed (keep only the operating system on the SSD) then when that happens you only need to replace the SSD that failed and reinstall whatever software you needed along the way (to fix the registry). Entire drive failure would mean the loss of an OS of which you should have a legitimate backup copy and nothing more.I did have the OS and data partitions separate, but that doesn't help when the entire drive dies
The operating systems should be on solid-state drives if available, and partitions if not. Either way, keep these things separate. Never mix operating-system partitions with anything else or you are just asking for trouble.
