SSD Configuration

[Leon Goldstein]

I know many of you have been using SSD's for many years so I'm hoping 
you guys can clear up some questions I have on how to use a SSD.  I have 
gleaned so far from various Linux fora a lot of confusing and sometimes 
contradictory advice on using trim.  Some say insert  "noatime,discard" 
in each partition line in /etc/fstab, others say to run trim as a chron 
job periodically, others say run trim at boot, while some say not to 
worry about it.

The next bit of confusion to me is "partition alignment" and/or 
"partition optimization."  How do you partition to obtain the desired 
partition alignment?

Bonus question:  is there a utility to trim Win XP?  I have Win XP on a 
computer and use it one time a year, when I install my tax software.  
I'd like to clone the drive containing Win XP as well as several Linuces 
to a SSD, after clearing up the questions I asked above.

TIA
