Title pretty much explains my question here. Anyway I installed a Samsung 840 Evo 250 GB SSD to use as a primary drive, back in July of this year. I went through a guide to optimise everything and one or two settings were changed in order to stop routine defragmentation of hard drives, for obvious reasons including to avoid damage to the SSD. How then do I look after my secondary HDD as I noticed it is getting a bit slower than in the past when it was a really good performer.
