Run them as you'd normally do, there's no need to complicate things. It's
state of the art technology and everything is basically done for you by the

That said, you should read these few links[1] and balance it out basically.
Alignment is what is most important when setting up the partitions for life
and performance. Other than that, ext4 mount flags and mindful use of high
I/O
operations is enough.

Has ssd quality improved that much?

Couple of years ago i replaced a normal hdd with a 30GB sdd, and
installed the distro on it. However, the swap certainly killed the sdd.

Even reading above links doesn't make me feel better, quoting:

"One can place a swap partition on an SSD. Most modern desktops with an
excess of 2 Gigs of memory rarely use swap at all. The notable exception
is systems which make use of the hibernate feature. The following is a
recommended tweak for SSDs using a swap partition that will reduce the
swappiness of the system thus avoiding writes to swap:
# echo 1 > /proc/sys/vm/swappiness"


So what they write is: Yes you can put swap on an sdd, but do not forget
to disable swapping. Not very helpful.
