Hey
@Dave Gas’ recommendations are pretty spot on.
An SSDs main advantage over a mechanical drive is not its transfer speed (3-4x faster), but its ACCESS speed (40-60x faster).
That means the SSD should contain those files your computer needs to
find or
change quickly and frequently. Game assets, the OS, audio/video assets that you are
currently recording/mixing/editing, cache files, your swap files, and so on. Your HDD is the place for stuff you want to keep on standby BUT not frequently use nor modify. Half-finished but suspended projects, media files, installers, ISOs, or most anything that is big or that you only ever use from beginning to end (like a movie).
Also, NEVER DEFRAGMENT A SOLID STATE DRIVE.
NEVER.
They don’t gain any benefit from defragmentation, in fact it actually wears them out faster.
