I have ssd + hdd on my laptop, - how to properly divide disks under systems, - under which partitions is it better to use sdd / hdd?

Question

linux

I have a dual hard drive. The system is installed Ubuntu 14.04, - I want to change it to ArchLinux (at first, only deliver it with the second system):

I have a question - under which partitions is it better to use ssd / hdd?
UPD1: Let's
simulate the situation (I have a large number of open tabs in the browser, and I want it all not to slow down):

Браузер Google Chrome использует память. Как он использует память? Какую память? Использует ли он файловую систему для хранения временных файлов или нет? -Использует только swap память или раздел /tmp на диске тоже?

At first I thought that I /tmpneeded it, - then I thought that it would be better to test the speed of ssd / hdd, - are there any programs specifically for this?
UPD2:
With what program is it better to divide disks?
When using LVM, will there be difficulties with grub later?
Question all the same:
How it is correct to divide disks?
How to properly divide disks considering all my UPDs?

Answer 1

For everything related to the system - SSD (if there is enough memory, I recommend mounting / tmp in general in RAM), large relatively rarely used files (movies, music, images, documents, archives) - on the HDD.

Answer 2

Yeah. Ubuntu has a performance testing program right out of the box.
In coffee tacos, I would transfer the system and configs from the hamster to ssd. Everything else is for pancakes.
/tmp in tmpfs
Everything.

I will share my fstab

Let me explain a little: / and all sorts of /usr on ssd and mount options such as data=ordered,discard... (there was a link to the arch wiki above). I note that the hamster is also on ssd, but not all, because. you can create a bin folder in the hamster and run applications from there - IDEs and other crap run in flight.
On pancakes, what we often have to write to, namely daddies with videos, music, etc., as well as /var and /srv, we mount via the bind option. /tmp put in memory.
