[mythtv-users] An SSD for Backend OS / Database Drives?

My Server's OS/Database HDD is possibly showing signs of aging being an
older and noisier 7200 120G that's got a few bad sectors reallocated.
Having found SSD on frontends give a significant user speed upgrade
(faster on/off and faster menu responses) I am now considering replacing
the backend OS drive with an SSD. (Also 3 x 2TB drives for recordings
seem happy there)
Some of the new 6G series 3 SSD's such as the Adata S510's seem a
possible replacement, capable of 550/510MB read and write speeds.
My motherboard (Gigabyte GA-EP31-DS3L)is a SATA 2 which I understand to
mean it can transfer 3Gb/s over the SATA interface.
There seems little point in spending extra on SDD's that run faster than
the SATA II interface, unless there is no disadvantage...
The b and B's might be confused somewhere, however it seems the full
550/510MB read and writes may be available on the SATA II interface.
If one uses a SSD on a backend (no frontend use) then the only
difference I expect I am going to see is faster mythweb page loads,
which might be nice for the recordings page. The frontend recordings
lists might also populate quicker. This basically assumes the database
reads are read from the disc and not from RAM, my understanding is its
done from the disc, if so there seems considerable scope for speeding up
the user experience that relies on the myriad of reads?
Can anyone comment about this analysis, do you agree or see it
differently? I presume some people have now done this, what has been
