For a Windows operation system, there should be at least two hard disk drive
partitions. One for installing operation system, the other is for storing files and
data. But normally, most people prefer to partition hard drive into
more than two volumes for managing their hard drives in a more efficient way. But
some restrictions have been applied in Windows. Partitions cannot be further divided
if there are four primary partitions existing already. As only a logical partition
can be divided into multiple extended partitions, we have to convert a primary
partition to a logical partition in this situation.
Another fact that may have been neglected by many users is that unaligned partition
will slow down the reading/writing speed of partition depends on various situations,
especially for SSD. The processing speed of SSD may be slowed down up to 15% if the
partitions are not aligned.
In short, as a user of Windows,partition is
extremely important that will directly determine the performance of your computer.
