Main Page Server Software Linux Linux-Storage LVM. ï»¿ Partition alignment is understood to mean the proper alignment of partitions to the reasonable boundaries of a data storage device (such as a hard disk, solid-state drive (SSD) or RAID volume). Proper partition alignment ensures ideal performance during data access. Incorrect partition alignment will cause reduced performance, especially with regard to SSDs (with an internal page size of 4,096 or 8,192 bytes, for example), hard disks with four-kilobyte (4,096 byte) sectors and RAID volumes.
PC Architecture limit is 4 partitions per physical drive. Drive letters though are a different story. There are three types of partitions: primary partitions, extended partitions and logical drives. A disk may contain up to four primary partitions (only one of which can be active), or three primary partitions and one extended partition. In the extended partition, the user can create logical drives (i.e. simulate several smaller-sized hard drives).
