For laptop, toss up. But remember, had a solid backup plan. For $50 a year, carbonite rocks!
SSD drives fare far better than flash drives as they have wear-leveling and backup blocks.

With a flash drive some blocks (directories in particular) get written far more than the rest of the drive and when one burns out the drive has had it.

With a SSD, though, the controller will sometimes move things around so that heavily-used directory block gets something put on it that almost never gets written. (Think of anything in Program Files for example.) Also, when a block actually does burn out the drive swaps in a spare and the user never knows it. Only when there are no more spares does the problem actually show up.

If the numbers are to be believed this should allow a SSD to have a multi-decade lifespan no matter how abused.
