> I=E2=80=99ve heard people say that Windows will soon wear an SSD out =
unless you turn swap off.

It depends on the amount of swapping vs. the device=E2=80=99s endurance =
obviously.

You should see what it does to performance AND monitor the wear through =
the smartctl tool or equivalent and decide for yourself.

(For Windows (and DragonFlyBSD ?) there=E2=80=99s the ReadyBoost feature =
that could work if you have a load of memory sticks kicking
 about.)
