Are there any thumbnail, indexing or memory tweaks?

I use a small SSD and a large HDD with over 100 GB of data I use regularly. HDD is slow and whenever I use Nautilus > Recent I'm being reminded why I hated HDD's so much :) It also happens that I have 7 GB of RAM that probabyl does nothing.

So, are there any Gnome settings that would allow to load indexing (search) database and thumbnail cache into memory, without resorting to something like https://wiki.archlinux.org/index.php/Profile-sync-daemon ?

What I mention above is mainly related to Gnome shell but if you know some lower-level tweaks for high-RAM systems, please share them. For starters, I don't use swap.

It doesn't address your question directly, but I've seen good results using the SSD as the journal device for filesystems on spinning media. man mkfs.ext4 covers the process well, but I can give you a walkthrough if you'd like to pose a topical question

I've used dconf-editor search function (ctrl+F) to find some relevant tweaks. Dconf-editor provides a clear explanation for every entry in-program, so I'll only provide entry locations/names.
(no entry listed - most are relevant or obvious)
org.gnome.desktop.privacy: recent-files-max-age , remember-recent-files org.gnome.desktop.thumbnail-cache

I've listed org.gnome.desktop.thumbnail-cache just to advise against decreasing the numbers as it won't benefit neither SSD nor HDD users. I've settled with recent-files-max-age set to 7.

Tracker settings
Settings of the Gnome indexing component can be customized using tracker-preferences.

Utilize HDD short-stroking and/OR smart data placement

TODO:
Investigate moving thumbnail cache and tracker database to ram(?). There doesn't seem to be any built-in provisions for this.

I do not know if what you are looking for, is what I did to increase the speed on my HDD.

Using Gome Disks that comes by default in gnome. http://greatk7.blogspot.com/2014/02/analise-de-disco-no-linux-com-o-gnome.html Following the steps that appear in the second image that appears at this link. click on the drive setting option. And goes the tab -> Write Cache.

Linking to your blog is probably fine, but can you provide the answer here too? If there's a link and no details, it just looks like spam.

@randomuser It's just Gnome disks > the settings cog > Drive settings. The blog entry looks fine to me. Heavy as hell though. Maybe too much NoScript and ABP :)

@Bucic - you've got that right - It didn't display anything for me :P

That's fine, @Gileade Oseiass - but you could at least say "Disable write caching, instructions are here" or whatever your blog instructs.
