Comment 3 for bug 574462

Hm, so my original workaround idea was to change /lib/udev/rules.d/85-hdparm.rules to

ACTION=="add", SUBSYSTEM=="block", KERNEL=="[sh]d[a-z]", \
        ATTR{queue/rotational}=="1", \
        RUN+="/lib/udev/hdparm"

to suppress the rule on SSDs.

But on Jarige's laptop this doesn't actually work, the attribute is "1" on the SSD (/dev/sda). It does seem to be correct on my Dell Mini, though.
