<title>Specifying Partition Alignment</title>

To specify the alignment of the partition, use the
<guilabel>Round to cylinders</guilabel> check box.
To specify the alignment of the partition, click the
<guilabel>Align to</guilabel> arrow button, and select from the list.

<para>
To enable, select the <guilabel>Round to cylinders</guilabel>
check box.
Use <guilabel>MiB</guilabel> alignment for modern
operating systems. This setting aligns partitions to
start and end on precise mebibyte (1,048,576 byte)
boundaries. MiB alignment provides enhanced performance
when used with RAID systems and with Solid State Drives,
such as USB flash drives.

To disable, deselect the <guilabel>Round to cylinders</guilabel>
check box.
Use <guilabel>Cylinder</guilabel> alignment to maintain
compatibility with operating systems released before the
year 2000, such as DOS. This setting aligns partitions
to start and end on disk cylinder boundaries.
</para>
<tip>
<para>
The Cylinder/Head/Sector values reported by modern
disk devices no longer have a direct physical
relationship to the data stored on the disk device.
Hence it is no longer valid to use this alignment
setting to achieve enhanced performance.

<listitem>
<para>
Use <guilabel>None</guilabel> only if you have an
in-depth knowledge of disk structure, partition tables,
and boot records. This setting places partition
boundaries relative to the end of any immediately
preceding partition on the disk device. This setting
is not guaranteed to reserve or respect space required
for boot records.

<para>
When enabled, <guilabel>Round to cylinders</guilabel>
aligns partition boundaries on the cylinder boundaries
for the disk device. Enabled is the default setting.

If you want to maintain compatibility with old operating systems,
enable <guilabel>Round to cylinders</guilabel>.
