But, for a SSD to fail, the cells have to exhaust their ability to be written. For most users, that would take many years to happen. Some have suggested that one replace a SSD once the warranty runs out, just like with the spinning drives. Laptops and most desktops have been shipping with SSDs for years now, and there hasn't been a problem. But, if you are worried about a drive just going belly up all of a sudden, that's why you always backup your stuff. We know most people won't do that, but that is not because of the technology, that's because of the user. I've read the opposite, that SSD today is faster and more reliable than the older ones. Any time a newer technology hits the mainstream, there are people who just naturally don't trust it. SSD has been around since the early 90s.
