Some have the ability of sample management wisdom. (not me) I do have an Intel 500gb that only has my "premier" libraries such as EW and VSL. The beauty of Kontakt is you can have libraries scattered across your system and it will remember where it is one you tell it. Most of the stuff in Komplete you find you rarely use it. Just start deleting those. To phase out my HDDs to SSDs is $$$$. I need to put that towards system upgrades since my Intel 4790 system and AMD FX system is not replaceable.
If you can only afford one 2TB SSD then put your favorites on it.
The sad thing is if you are into gaming your 500gb SSD drive doesn't cut it anymore because of lazy developers who think gamers could not handle compressed video. They could never get a job at Cockos.
