The wikipedia article on flash media talks of up to a million cycles.

You have to look at the hours of use, not the years. On a laptop it
seems that 4000 to 6000 may be the limit, whereas on a desktop 10000 to
20000 is typical (mine have 12000).


lucky you!

My Corsair 60GB SSD from 2008/9 (?) gave up irrecoverably with approx. 4000 hours during only 3 periods of 6 month over 3 years (with pauses of 6 month unused).

Wait.

My first paragraph above refers to flash media; the articles mentions 10000 cyles for some media, 10⁵ for better media, and 10⁶ for even better media.

And my second paragraph refers to standard magnetic media.


Maybe nowadays SSD are much better, don't know. It's not a time where things generally get better :-)

I guess they improve. Just read another paragraph in the wikipedia where they say that Macronix is working on a device that self heals itself with "heaters" inside the chip, improving cycle expectations to 100·10⁶. There are no comercial chips of that class yet.

http://en.wikipedia.org/wiki/Flash_memory#Memory_wear - search fo Macronix
