Just be aware that SSDs wear out. They have a limited number of write
Nowadays they all do 'wear levelling' to even the writes across the drive
even so they don't last very long in heavy write usage.
If you're talking swap and tmp then you can get a DRAM drive which will be
lightning fast but even with battery backup you can't expect the contents to
be kept through a power cycle.
