With XP doing a format the partite aligning is not correct for ssd , there are several ways to get good partition aligning .
Make the partition with Gparted , this utility can also correct bad aligning follow the steps in the helpsection http://gparted.sourceforge.net/
It is possible to connect the ssd to a pc with W7 or W8 beta and create the partition in windows, that is the easy way .
The ASSD benchmark utility checks aligning without doing a benchmark http://alex-is.de/PHP/fusion/downloads.php?download_id=9
Very useful is a streamlined xp with Intel sata/raid drivers http://www.nliteos.com/
In the bios the setting for ssd is best set on ACHI/RAID ,not the IDE setting .I recommend the raid setting even for a single ssd .
Now install xp on the ssd , use the good aligned partition made earlier . When ready, install the Intel Toolbox
The toolbox for tweaks and the use of optimizer , XP has no trim . Good aligning is the most important thing
Several tweaks can be found with the ssd tweaker utilitie http://elpamsoft.com/Downloads.aspx?Name=SSD%20Tweaker
