Much of the items that will end up on an SSD are already long lived. Every gigabyte of RAM runway before flushing items reduces the write load, since recent items are at highest risk of being overwritten/deleted.. also stuff with shorter TTL's won't be persisted (or can be persisted to bucketed pages for avoiding being compacted). TL;DR: there's a lot to it and I'll be going into it in future posts. The full extstore docs explain in a lot of detail too.
