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:

wmic partition get BlockSize, StartingOffset, Name, Index

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