We need more people to get SSDs for the "trial and error" since SSDs are not near perfect in term of durability as the HDDs are(reads/writes limit). And more people using this technology means that companies making SSDs will have a "bigger pot to pick from" so the technology behind SSDs will mature even faster, like the transition from magnetic to optical storage did.
Please excuse me for my grammar or spelling errors there since i tried to make an analogy from my language to english. Plus, i hope what i wrote made sense in a way.
