I think I''ve read in a number of early SSD reviews
(possibly regarding Intel devices - not certain now)
that the vendor provided some low-level formatting
tools which essentially allowed the user to tune how
much flash would be useable and how much would
be set aside as the reserve...

Perhaps this rumour is worth an exploration too -
do any modern SSDs have similar tools to switch
them between capacity and performance modes,
or such?
