PettyOfficer - an SSD does not "run" in the conventional hard drive sense; it has no moving parts. I haven't heard of the faster read/access speeds being linked to failure. They do alow for less writes as mentioned, meaning repeated Move, Copy, Save, Delete can cause failure sooner than a typical spinning platter HDD.
With current price and size limitations they are best used for operating system and application drive only. My collection is also about 2 titles per 1GB at 16-44.1 res FLAC. I run an old laptop with 250GB HDD to fit that - reliable SSD that size would cost more than the laptop :-)
