Yes, these SSDs can write many times. They use some algorithms to keep writes roughly equal across all the elements, plus it can automatically map bad ones and remove them.
blah...I did some googling and found this article:

It's really poorly written, but to jump the meat of it.

That's a meaningless number - which needs to be divided by seconds in an hour, hours in a day etc etc to give... The end result is 51 years! | |

So basically, it looks like any single 'sector' or whatever has 2 million writes before it dies (average). Due to wear-leveling algorithms, you would basically need to write the size of the drive 2 million times. At an 80MB/sec write speed, that's 51 years of writing at max throughput, 24 hours a day, 365 days a year, for 51 years. So yea, I think they fixed that problem. :p Of course, that assumes a 64GB capacity. Drive endurance goes up as capacity goes up.
