Once you have installed the operating system on the server's hard disk, the hard disk structure is in its basic configuration. This means that the basic disk configuration is organized into partitions. As you now know (see the Understanding partition schemes section in Chapter 3, Installing Windows Server 2019, for more information), the basic disk is based on the MBR and GPT partition schemes, and, as such, one partition cannot be extended on one or more physical disks. Instead, a partition can be extended by adding unallocated space from the same physical disk.
Now, let's learn about dynamic disks so that we can understand how read-write performance can be increased.
