I have been told that with Intel drives it isn't needed.
Where did you hear this? I do not think this is correct. I am relatively new to SSDs but I'm pretty sure that any XP partition will need to be aligned when transfered to an SSD. Something about the number of sectors at the beginning of the partition not matching up with a whole block on the SSD causing everything else to be misaligned.
Not to hijack the thread, but I'm looking through a bunch of SSD related threads right now to see if/how I can transfer a Win7 partition to an SSD...
