Re: [opensuse] Get an SSD just for swap?

As this is for swap only, I can get a cheap SSD (if it breaks I just
lose one session). I can get a 32Gb SSD for about 25 Euro, while an
extra 8GB of RAM would apparently set me back more like 50 Euro. But
will this work?

In those circumstances I'd go for more memory first.
late model Linux doesn't have a hard boundary between buffer space and program
space any more, so it figures out where best to use the memory according to
circumstances.

Swap is used ONLY when there isn't enough memory.

I'll grant you that maybe you'll still end up with not enough memory, but when
that happens to me I've always traced it to

a) a memory leak

I got a lot of those with Firefox and Thunderbird plugins.
I suspect I still do If I really try to have too many open tabs in Firefox.

b) too many open ... whatever.

Usually tabs in Firefox but it also applies to open files, file saves and
general thrashing in LibreOffice if I have other programs open, Gimp if ...;
darktable if ...; KMyMoney if ...

That may be a kernel problem.
Shutting down ... Firefox ... solves the issue.
Very occasionally the whole machine is unrecoverable, but I think that too is a
kernel issue.
I don't know how to track this kind of problem for bug reporting.
But then I only have 4G on this Mobo. Technically, the manual says that I can't
go above 8G, but the 4x4G are rather expensive. I do know someone who does run
that on this Mobo.

Of course I could upgrade a Mobo; after all DDR3 is a lot cheaper than the DDR2
that this Mobo uses. Last time I looked it was a marginal decision. Maybe I'm
in line for a Christ present.
