..and the past two years were "early days" for SSDs in the mainstream, with a number of bugs exposed and fixed. Todays drives and firmwares appear to be rather rock solid. Much more so than the mechanical drives out there.

But yes, one big difference, is that when an SSD fails, generally the entire unit fails. With mechanical drives, one sometimes gets advance notice in the form of bad sectors, as the dust particles bounce around inside randomly scratching sectors until the whole thing konks out.

But total/sudden electronic failure is also common for mechanical media, as are firmware bugs (eg. Seagate last year).
