ssd data storage problem!

[Muneeb Ahsan]

I read somewhere that SSD can store data up to a exact number of data erase. After reaching to that number the write operation on SSD won't work. Please do tell me how much it is true and if its wrong then what's the true theory.

It wrong, mostly. The number of erase cycles is an estimate of how many erase cycles a cell can withstand. Some cells fail early and some live much much longer. Over provisioning your drive allows for the SSD to use spare cells in place of ones gone bad as well as providing 'working room' for garbage collection and trim

you mean to say, cell can be damaged but it can't be any serious thing?

Like light bulbs, some fail suddely without warning while others seems to last forever. But all lightbulbs get dimmer the more they are used, you just might not notice until you replace it and think 'Wow this is brighter".

The same things happen with storage cells and the SSD controller monitors all of them. Cells get used when you write to them, reads don't have an impact of a cells lifespan. When one begins to have a problem it tries to rescue the data and then marks the cell bad and wont try to store things there anymore. Hard drives do the same thing. You might have heard of bad sectors and remapped sectors.

If a cell fails and the info in it cannot be saved then this may or may not be an issue, depending on what what is it.
It might be a much needed windows file which causes you to not boot up anymore or it might be something in your recycle bin that you don't ever use anyways.

got it. but one more question ssd controller fix all the problems of bad cells on their own or we have to use some kind of third party application to do that.
