SSD - ways to lower written data (LBA)

What ways are there to lower the writes to the SSD disk (LBA´s written)?

I have heard that some functions turned on can write a considerable amount of data to the disk.

I have already turned off the safe sleep mode.

How about journaling, how does that work, does journaling write anything regularly to the SSD / hard drive?

I would appreciate some tips and tools on functions that writes a not too small of an amount of data to the SSD and which can be disabled?

I´m using High Sierra and a MacBook Pro late 2011 with a 512GB SSD as primary boot drive, and a second 2TB Harddrive in the optical drive bay.

Why on Earth would you want to do that? Because you read somewhere that solid state memory is write/erase cycle limited? You will never reach that limit over the life of your Mac. I have OWC SSDs older than your Mac that still work as well as the day they were new. SSDs from other manufacturers might not. You get what you pay for.

AFPS does not use journaling.

Let your Mac work the way it was designed to work.
