Free/Best Disk Partition Tool for Windows Server 2019/2022

by John, Updated on: January 3, 2025

A hard disk drive is an indispensable component in a server, whether you are using a mechanical disk, a solid-state drive (SSD), or any type of hardware RAID array. Before saving files to a brand-new disk, you should initialize the disk, create partitions, and format them. After running the server for a period of time, you may need to shrink a large volume to create additional ones, expand a volume when it is running out of space, or copy and replace the disk with a larger one. Therefore, you need a reliable disk manager for the server to help accomplish these tasks. This article introduces free and the best disk partition tool for Windows Server 2019/2022.

Free Disk Management tool in Server 2019/2022

The same with previous versions, Windows Server 2019/2022 has 2 native tools to help manage disk partition - Disk Management and diskpart. Disk Management (diskmgmt.msc) has graphical interface, it is able to create, delete, format partition, set partition Active, change drive letter and path. Diskpart is a command prompt tool, it can do the same thing in a different way.

What does Disk Management do in Server 2019/2022

Disk Management

To an allocated partition, the options include:

  • New Spanned Volume
  • New Striped Volume
  • New Mirrored Volume
  • New RAID-5 Volume
  • Convert to Dynamic Disk
  • Convert to GPT disk
  • Offline
  • Properties

Disk Management

To a disk, the options include:

  • Open root directory in File Explorer
  • Mark partition as Active
  • Change drive letter and path
  • Format
  • Extend Volume
  • Shrink Volume
  • Add Mirror
  • Delete partition
  • Properties

Disk Management advanced feature

Change partition size:

The same with previous version, Server 2019 Disk Management has Shrink Volume and Extend Volume functions to help resize allocated partition without losing data (in most cases).

But because of some limitations of both functions, Disk Management cannot extend a partition by shrinking another one. In addition, only NTFS partition can be resized.

Disk conversion:

Disk Management has the option to convert disk between MBR and GPT, convert disk between basic and dynamic.

However, it can only convert basic disk to dynamic without losing data. To convert dynamic disk to basic or convert between MBR and GPT, you must delete all partitions beforehand on the disk.

Manage dynamic volumes:

Server 2019 Disk Management is able to create and manage Simple, Mirrored, Striped, Spanned and RAID 5 dynamic volume.

Dynamic disk volumes consume significant server resources, and if one disk is damaged, all data in the volume will be lost. Hardware prices are much lower now, so most servers use hardware RAID arrays instead of dynamic volumes.

The safest disk partition tool for Windows Server 2019/2022

There are many disk partition software for Windows Server 2019 and other versions in the market, the GUI and functions are all similar. Different with data read-only program, disk partitioning software will modify the parameters of associated disk, partition and files. So there's potential system damage and data loss risk especially when you shrinking, moving and extending partitions. You'd better make a backup first and run the safest tool.

The fastest disk partition software for Windows Server 2019/2022

When selecting a disk partition tool for Windows Server 2019/2022, there’s another factor you may overlook: speed. For example, when shrinking a partition from right to left or moving a partition, the start position of the partition will change, and all files within it will be moved to new locations. The more files there are in the partition, the longer the process will take.

Thanks to its advanced file-moving algorithm, NIUBI Partition Editor is 30% to 300% faster than other tools. This is especially helpful when there is a large number of files, and the operations require the server to reboot in order to complete.
