HDD and SSD both work pretty hard at hiding physical limitations from
the abstraction they present to the OS. The only way to get lower-level
info is S.M.A.R.T, as far as I know.
But, unless your use of SSHs is very atypical, there's no reason to
worry about it. E.g. the "problem with too many writes to the same
blocks" is solved by the SSD's wear-levelling algorithm.
