Jautājums
SuperUser lasītājs Nzall vēlas uzzināt, kāpēc SSD nozarēm ir ierobežots skaits rakstzīmju:
I often see people mention that SSD sectors have a limited number of writes before they go bad, especially when compared to classic (rotating disc) hard drives where most of those fail due to mechanical failure, not sectors going bad. I am curious as to why that is.
I am looking for a technical yet consumer-oriented explanation, i.e. the exact component that fails and why frequent writes affect the quality of that component, but explained in such a way that it does not require an extreme amount of knowledge about SSDs.
Kāpēc SSD sektoros ir ierobežots skaits rakstzīmju?

Sekojot MonkeyZeus atbildei:
Imagine a piece of regular paper and a pencil. Now feel free to write and erase as many times as you please in one spot on the paper. How long does it take before you make a hole/tear in the paper? SSDs and USB flash drives follow this basic concept, but at the electron level.
