For comparison, for a while we nearly had a 1 to 1 dev to killed (consumer) SSD in work machines (see: http://blog.codinghorror.com/the-hot-crazy-solid-state-drive...). Granted, we did adopt them (see: http://blog.codinghorror.com/the-state-of-solid-state-hard-d...) for local dev use much earlier than we started putting them in servers.
I've killed 2 in my time here, though I do horrible big-ish data things that are either not SSD friendly or actively hostile.
