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?

Formatting has nothing to do with sector alignment, you still need a 4k aware OS. See… – Moab Jun 6 '11 at 22:02

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.

What if I migrate Windows 7 from old HDD to new SSD? Do I need to perform alignment and how? – Boris_yo Aug 26 '12 at 15:02
Windows 7 uses the same alignment for both HDDs and SSDs so as long as you let Windows 7 align the HDD the alignment should be preserved during migration. – Mr Alpha Aug 26 '12 at 15:24
Thanks, I understand that alignment is only relevant for Windows XP. Not sure about Windows Vista though... – Boris_yo Aug 26 '12 at 15:41
Vista deals with alignment the same way 7 does. – Mr Alpha Aug 26 '12 at 15:43
And all previous versions prior to Vista need to be aligned. Got it, but what about Linux? Which distribution and of which version starts aligning SSDs? – Boris_yo Aug 26 '12 at 16:28
