Thanks for the warning Ben. I'm somewhat familiar with the limitations and I was initially worried about the life expectancy of a tpical SSD also. However, it appears that most of the initial hype over the write limitations of SSDs has died down due to the wear levelling algorithims incorporated on most of the enterprise SLC SSDs. Some of the EFDs (Enterprise Flash Drives) EMC uses in the DMX4 claim 2 million write cycles per cell. But there shouldn't be much worry over a typical SLC SSD that can handle 100,000 write cycles per cell either.
