First, there is zero need for any "realightment". You are using Windows 7 which correctly handles alignment.
This is only the case if you fresh install win7 on ssd (as he did with win7 personal). win7 work ssd has been cloned so not aligned!!

SSD Storage Demands Proper Partition Alignment
sdd blocks are 128KB
ntfs disk clusters are 4K.
So 1 SSD block has 128/4=32 ntfs clusters
If win7 reads or writes something it does this for the whole cluster.
SDD treates 128KB as a block that is readable/writeable.
If not aligned properly... first and last ntfs cluster on EACH ssd block belongs to 2 SSD blocks.
2/32=1/16=6,6% ssd performance loss. And SSD life time will be shorter.
You're going for speed.... align!!!
