How to properly install linux on SSD?

Question

linux

There is an OCZ Vertex3 120GB SSD, it worked successfully with Windows and OS X, but with Linux there are some difficulties in the form of enabling TRIM, etc. With this, in principle, you can easily figure it out just by googling and I'm interested in the moments that I did not find (MB searched badly).
As I understand it, in order for the SSD to live for a long time, you need to move some of the directories to some HDD so that only the system is on the SSD. Is it necessary to do this? If everything is done, but the HDD is broken / lost / (it will not be possible to use it), will the system break down (refuse to boot)? If you connect the HDD to another SATA port, will everything be fine or will you have to reconfigure everything?
I put the system with the expectation that I will use it for a long time, and that there will be no surprises. In the future, perhaps, the SSD will "move" to the laptop and there will most likely not be an opportunity to connect an HDD as well.
I use the SSD as a regular HDD, i.e. I create files, folders on the desktop, something for development (web dev, android) is also all on the SSD. And I just don’t know how comfortable it will be to work on Linux with all these troubles.

Answer 1

For some reason, everyone takes care of the SSD, trying to read / write as little as possible. That's just an average SSD starts to fail somewhere after 500TB of reading / writing data. For example, in half a year I managed to write only 3TB to my SSD, actively using it (Windows and all programs). In other words, the SSD will die earlier from old age.
In general, throw everything on the SSD, except for music / video / photos, because they take up a lot of precious space for the SSD, and high speed will practically not affect them.

Answer 2

I use a laptop with 2 disks, I have everything mounted like this:
/dev/sda1(SSD) mount to /
/dev/sdb1(HDD) mount to /home
In your case, if the HDD can disappear altogether, then as an option you can mount HDD somewhere in / media
and there, for convenience, make sim links to the necessary directories such as "downloads", "video" from the home directory.
So in case of HDD death, you will lose only garbage, but you will not lose all the configs from the software that are in /home/$user.
Yes, and as practice shows, SSD still lives longer than any HDD, since the latter will crumble faster than the first overwrite cycles will end.

Answer 3

System, swap file, home directory - on SSD.
Everything else is on the HDD.
That is, the principle is simple - on ssd we store files that are often read or changed, and on hdd rarely used files, archives, files, access speed to which is not critical.
The only optimization that can be done is to leave about 5-7% of the disk unallocated.
This will not affect the resource in any way, but it will eliminate problems with a drop in write speed, because the disk will always have a supply of clean cells. Especially useful in the absence of trim.

Answer 4

My SSD from OCZ has a 3 year warranty. You probably do the same. The question is what are you up to?
