Because we all know what security is, please don't entrust your bitcoin wallets ONLY on SSD drives. They tend to fail too... What's more important is, that they're harder to recover. 

I have backups of the wallet. I run Bitcoin off of the spinning disk because space and because it's not my primary wallet anyway. I'm actually considering moving away from running a full node.
I don't run a full node because I sync my cold wallet only once every 6 months or longer. I once ran one at work though.
