+1 to the SSD's being designed more for reading than writing. Mine is old enough that I have learned it hates to unzip massive files (such as SONAR's installation files). This makes it blue screen me (but again is a 2011 model). Also be aware that SSD's have a few "don'ts" with them as far as maintenance - a good list is
here. I have not been following SSD development, and it is maturing quickly; but writing to sectors repeatedly (such as defragging often) degrades the memory cells in ones like mine.
+1 also to the recommendation for magnetic backups. They will retain data till the cows come home without power, are dirt cheap these days, and are a more mature product.
