Do ssd's get bad sectors as HDD'S? My question is very simple, do ssd's get bad sectors overtime like normal HDD'S, if they do, do they spread like normal HDD'S increasing overtime? or do ssd's have another way to tell when they are dying?
In my experience with SSD, gates can fail, and data blocks will be relocated to sequential gates that do not have failures. Not quite the same as an entire sector but along the lines just on a smaller scale. Now, the biggest difference is that a gate on a SSD can be overwritten a multitude of times more than any single location on a HDD before failure is to be expected. Its really like thousands of overwrites compared to just a few dozen overwrites. HDD are sectored and SSD are not, when a bit space fails on a HDD then the entire sector is isolated, when a bit space fails on a SSD it is only the single bit space (gate) that is isolated and the very next space if sequential to an entire possible block, can still be used. So, if you have a thousand failures in different sectors on a HDD then the whole HDD is shot. If you have a thousand failures on a SSD then there still could be 99% of the drive still useful. It is all reliant on how fragmented the drive has been during most of its writing.
