Should I convert to dynamic disk?

Frankly speaking, converting basic to dynamic disk will improve the performance for your Windows operating system. But there are some situations you could not convert to dynamic disk:

  • When downgrading your Windows operating system;

  • Multi-boot environments (converting will cause problems If you have more than one operating system);

  • Unknown partitions like OEM partitions (it’ll be inaccessible after converting to dynamic disk).

  • Your Windows operating system not support dynamic disks.

Except for these situations, you could consider to convert basic to dynamic. But before converting, you must have enough understanding of the two disk storage types: Basic disk, Dynamic disk.

Basic VS Dynamic disk

The basic disk means a disk that contains partitions, like primary partitions, logical partitions. It supports both Master Boot Record (MBR) and GUID Partition Table (GPT) partition styles. Basic disk volumes consist of one set of contiguous extents on a single disk. Basic disk is the storage types most often used with Windows.

Dynamic disks has the ability which basic disks not supported to create volumes that span multiple disks like spanned and striped volumes, and is capable of creating fault-tolerant volumes like mirrored and RAID-5 volumes. It also supports both MBR and GPT partition styles.

The most important thing is Dynamic disks offer greater flexibility for volume management, because a database used to track the information about dynamic volumes and other dynamic disks in the computer. Besides, dynamic disk is compatible with all Windows OS from Windows 2000 to Windows 10. You could create volumes up to 2000 dynamic volumes on a system (recommended number is 32 or less).
