I decided to upgrade my notebook to SSD disk. The disk replacement went easy, installed fresh Debian on it and now comes the tricky part how to properly tune system to use as much as SSD can provide.
The first obvious thing for me is changing IO scheduler. But which one to choose? Most of howtos seem to suggest noop or deadline, without stating benefits of each. For now I've chosen deadline, without string coninfidence, that I'm doing the right thing.
The next major part of tips includes removing filesystem journalling. Well I think journalling exists for good reason and disabling it won't help me much (no, I really don't want to wait for fsck after each crash).
The last tweak seems to be using tmpfs for any temporary data (/tmp) or even for logs. For /tmp it might make sense, on cost of loosing available memory (or swapping it out, what really does not help the SSD anyway). However I definitely don't want to loose my logs on every reboot.
Maybe I'm missing some bit, but the only important thing seems to be the IO scheduler.
