I have a couple of laptops that I use for recording and a PC that I use for mixing and mastering and an external 500GB SSD with all of our recorded work plus works in progress, this includes all raw stems and the Reaper project files which are in turn backed up to a 1TB external spinner, this being a manual process when I remember to..
Just before Christmas the USB ports on the PC decided that they would go haywire and have made the SSD unreadable which is an absolute pain in the whatsit as I hadn't backed up the last 6 weeks of mixing and mastering.
I've had EaseUS doing a sector level deep scan with the objective of recovering the drive since boxing day and it's currently up to 386,269,184 sectors out of a total of 976,7687,065 so probably around another 2 weeks of scanning before the recovery process an begin.
Moral of the story, if you are doing anything critical on a PC such as music of video production running a SAN with RAID is critical.
Given that I spent the final 25 years of my working life designing stuff that was not only mirrored on site but mirrored across multiple sites and also had RAID storage across multiple sites I should know better
