I remember hearing some years ago that one limitation to solid state drives was that writing and deleting too repeatedly could become detrimental to the overall performance and/or storage of that drive. How far have we come? Does this still hold any ground? Or is it a non-issue now, similar to the old worry of burn-ins with plasma tvs? I'd like to be able to use Bit-Torrent on my MBA, but with the capacity of only 256GB I would find myself having to constantly free up space. No good? Or no worries?
