I have many HDDs connected to my computer and it runs 24/7.

My unit has an SSD system disk and 12GB RAM.

Will adding more RAM speed things up, or is some limit reached with
extra RAM?


It's not a matter of a limit. Whether it will make your computer
faster or not depends on what programs you run, and with some programs
graphics editors, video editors), how big are the files you use with
them. For *most* home users, 12GB is more than enough, and adding more
RAM will do nothing.

It's as I feared. My machine runs Windows10 pro 64bit.
The motherboard...
Ga-x58a-ud7_v.2.0 (2010)
...has almost all PCE & PCEe slots used, feeding HDDs & USB3 cards
(which suppy still more HDDs.)

Should I overhaul things by installing a new motherboard, (which?) or
would a satellite computed be more efficient?
