Theoretical reliability and lifespan is much higher than that of mechanical drives. There have been bad "batches" of SSD drives from one or two companies, but there are from mechanical drive companies too. "Thus Intel will guarantee that you can write 100GB of data to one of its MLC SSDs every day, for the next five years, and your data will remain intact." http://www.anandtech.com/cpuchipsets/intel/showdoc.aspx?i=3403&p=4 http://www.anandtech.com/cpuchipsets/intel/showdoc.aspx?i=34... People should have backups anyway, so I guess if the companies are standing behind these drives and all the users so far are pleased it's not really an issue, though it doesn't beat the mech drives really (although in mobile applications shock resistance is higher) but there seems to be no cons. It's just price, size and speed to decide on them now. Still, given the prices, for home applications I imagine people just want a boot drive and storage on a larger mech. On the server side there are probably quite a few databases that could benefit from 1TB with good random access and throughput.
