Basic disk VS dynamic disk

Basic disk and dynamic disk are two kinds of storage type. Both of them support GPT and MBR disk. But they differ in many aspects:

  • Basic and dynamic disk employ different ways to track information: basic disk use partition table while dynamic disk uses LDM (Logical Disk Manager) or virtual disk service.

  • Basic disk can hold primary partition, extended partition, logical partition while dynamic disk can contain simple volume, spanned volume, striped volume, mirrored volume, and RAID-5 volume.

  • Basic disk can be supported by all Windows OSes from MS-DOS to Windows Server 2019 while dynamic disk can be used in Windows Server OSes, Windows 10/8.1/8/7, XP and Windows 2000.

  • You can own dual-boot or multi-boot environment on basic disk and dynamic disk doesn’t support dual or multi-boot environment.

★ About different kinds of volume in dynamic disk
▪ Simple volume: It likes the primary partition in basic disk.
▪ Spanned volume: It allows you to combine multiple unallocated spaces go across different physical disks.
▪ Striped volume: It can improve read-write performance as it distributes I/O requests among disks.
▪ Mirrored volume: It can create a copy of data in a mirrored volume to protect data.
▪ RAID-5 volume: RAID 5 is a redundant array of independent disks that uses disk striping with parity.

After realizing the differences between basic and dynamic disk and deciding which one to choose, let’s go into how to manage basic and dynamic disk.
