====== Disk Partition Alignment ======

===== Windows =====

  * Misaligned partitions result in additional disk IOPS, sometimes double
  * Windows XP and older creates misaligned partitions by default
  * Newer Windows and Linux OS's create properly aligned partitions

==== Check Partition Alignment ====

In a command shell with admin privileges:

<file>
wmic partition get BlockSize, StartingOffset, Name, Index
</file>

**If the number isn’t a multiple of 65536 (64 kB) or 1048576 (1 MB) the partition is unaligned.**
