As I see it now, it will be really the Soft-RAID what will suit for
everybody here (including me) as well.

What I see from them is that they supported wear-leveling before
wear-leveling was included into the drives. Currently I have a 16G
SLC-based Swissbit CF-card. Practically the only high-tech part.
Personally I have no practice with any flash file systems, so I would
stick to ext3. Well, I wouldn't say I would have much more expertise
with ext3 and soft-RAID.

Well, I've worked a bit with Oracle before, so PG is quite handy for
me right now. Practically this decision was made before my arrival, I
was basically asked, if I can learn PG too. I'm learning...
PG - and database - was the decision because the flat files were
managed over 15 years, sometimes partly rewritten, revisited and my
real job is to adjust some in the application code as well for the
configuration part of the DB. Guanistical software development :)
