Your points are well noted, although on the flipside I've had an SSD
perform horribly because without TRIM, it had to use its own garbage
collection which was horrible. Also, if you rely on garbage collection, you
need to make sure to make an empty partition with 5 or 10% of your space and
never use it so that yoru SSD can easily use that for garbage collection
without impacting performance too much.
