I just got a new SSD drive (OCZ Vertex 2) and installed Windows 7 on it. Problem is, now I need to install XP also for some legacy applications that I run. I read here, among others, that XP has partition alignment issues when creating a new partition, that can lead to huge performance drops and increase the wear of the drive. The suggested remedy involves tuning the partitions with DISKPART. I was just wondering, will it be OK if I create a new partition from Win7 (which supposedly doesn't suffer from this issue) and then install XP on that?
Yes, that will work fine. Windows 7 will automatically align the partition properly, and the partition will remain aligned when you install XP onto it.
