Solid State Disks require partition alignment to 4KB boundaries for optimum performance and life.

Partition alignment and Solid State Disks (SSD) Partitions start on a head (or track) boundary and end on a cylinder boundary. Disks are described as having sectors, heads and cylinders, typically 512 bytes per sector, 63 sectors per head and 255 heads per cylinder. This is the alignment used by all Windows versions, up to and including Windows XP/Server 2003. Cylinder, Head, Sector (CHS) alignment.For a disk with 512 bytes per sector this equates to 2048 sector alignment. Beginning with Windows Vista/Server 2008 partitions are aligned on 1MB boundaries. There are two alignment possibilities used by Windows: Partition alignment refers to the physical sector offset of partitions. This week for Techie Tuesday we’re covering partition alignment.
