There was one with a dude throwing it off the roof of the building into the car park and it still worked too.

That's very different than long term reliability. They can certainly take shock well, the problem had to do with repeated write cycles.

[citation][nom]cjl[/nom]It's true, but different chips have very different lifetimes. These drives are designed for an enterprise environment, and because of that, they use the faster and more durable (and more expensive) SLC flash, rather than the MLC found in most consumer-level drives. Based on Anand's preview of these drives, they should be able to run at full sustained write speed for 5 years without dying. That's not 5 years "at typical usage patterns" - that's 5 years of writing as fast as you can.[/citation]

Wow, thanks! I found this:

How Long Will They Last

I am very close with many SSD manufacturers of both the enterprise and consumer arena. I have asked this question of many and must admit that the most frank response is “MLC lifespan is a little sensitive with manufacturers. Each is trying to cope with this answer very carefully.” The true answer to the question for both slc and mlc SSDs is this…

“The SSD will outlive the hardware for which it was built for.”

SLC ssds can be calculated, for the most part, to live anywhere between 49 years and 149 years, on average, by the best estimates. The Memoright testing can validate the 128Gb SSD having a write endurance lifespan in excess of 200 years with an average write of 100Gb per day.

This is where the mlc design falls short. None have been released as of yet. Nobody has really examined what kind of life expectancy is assured with the mlc except that, it will be considerably lower. I have received several different beliefs which average out to a 10 to 1 lifespan in favour of the slc design. A conservative guess is that most lifespan estimates will come between 7 and 10 years, depending on the advancement of ‘wear leveling algorythms ’ within the controllers of each manufacturer.

To draw comparison by way of write cycles, a slc would have a lifetime of 100,000 complete write cycles in comparison to the mlc which has a lifetime of 10,000 write cycles. This could increase significantly depending on the design of ‘wear leveling’ utilized.

Very interesting indeed
