Yeah and Titanic was unsinkable.
If the controller in your SSD fries, it doesn't matter how many unused gigabytes your SSD has got for relocating bad sectors. It is still fried. For you, that data is forever gone.
This is why you have redundancy. Full redundancy. You can go for RAID1, one disk die and you still have no data loss, or go bananas with RAID6, two full disks can die and you're still going strong.
Ps. Spinning harddrives have had hidden sectors used for relocation of bad sectors for ages. It's nothing new. If you have to much time on your hand, Google harddrive hidden sectors nsa.
