Option 2. Change cluster size from 4K to 64K with Disk Management
Disk Management is a Windows utility tool that allows users to perform various disk-related tasks, including changing file systems, creating partitions, formatting drives, and more, as well as modifying the block size.
Here's how:
Step 1. In the "Start" menu, type "Disk Management."
Step 2. Right-click on the drive whose cluster size you want to change.
Step 3. Select "Format."
Step 4. To allocate a unit size of 64K, click on the "Allocate unit size" drop-down menu and select "64K".
Step 5. Begin formatting your drive now.
Disk Management is a tool provided by Windows that allows users to manage disk partitions and formats, as well as perform other tasks such as creating, deleting, and resizing partitions.
Option 3: Change cluster size from 4K to 64K using File Explorer
You can change the cluster size of a hard drive using File Explorer.
Here's how:
Step 1. Open "This PC."
Step 2. Select the disk whose cluster size you'd like to change.
Step 3. Right-click the disk and select "Format."
Step 4. Select "64K" from the "Allocate unit size" drop-down menu.
Step 5. To format the drive and change the cluster size, click on "Start".
Option 4. Change cluster size from 4K to 64K via CMD
The Command Prompt is Windows's command-line interpreter, allowing users to perform various commands and troubleshooting tasks.
To change the cluster size using the command prompt, you can use the `fsutil` command. The command to use is `fsutil file setquota < drive> < cluster>`, where `< drive>` is the letter of the drive you want to change and `< cluster>` is the new cluster size you want to set.
Step 1. To open a command prompt, click "Start" and type "command prompt" into the search bar.
Step 2. Select "Run as administrator."
Step 3. Now type the following commands by pressing the "Enter" key to change the cluster size successfully.
- diskpart
- list disk
- select disk x (To change the cluster size of a disk, you can use the `fsutil` command with the `fsutil fs setquota` option. For example, to change the cluster size of disk X to 16 KB, you would use the command `fsutil fs setquota X 16`. This will set the cluster size for the specified disk to 16 KB.
- list partition
- select partition m (m is the partition number for which you want to change the cluster size).
- format fs=ntfs quick unit=64k
What Is Block Size and Cluster Size
Block size and cluster size are two separate concepts in computing, particularly in file systems and storage management. Block size refers to the smallest unit of data that a file system can read or write, usually measured in bytes (e.
A block is a unit of storage where data can be written to or read by the drive, while a cluster is the amount of space allocated for a file, often taking up multiple blocks.
The main difference between block size and cluster size is that block size is a logical attribute of the file system, whereas cluster size is a physical characteristic of the storage device.
A smaller cluster size can improve performance for small files, but may waste disk space. On the other hand, a larger cluster size may slow down the performance of small files, while improving the efficiency of large files. Typically, a standard cluster size of 4096 bytes (or 4K) is used, striking a balance between these competing factors.
For most workloads, using a cluster size and block size that strikes a good balance between performance and efficiency is ideal. If you need to optimize these settings, a guide is available to help you find the most efficient solution. You can also share this information with others if you find it useful.
Why Change Block Size From 4K to 64K
A 64K block is a unit of storage that is 64 kilobytes, often used in file systems to store large files, being a multiple of the standard 4K block size.
Larger clusters allow more data to be stored per cluster, reducing the time the hard drive head must physically go through from cluster to cluster, and a 64K block size prevents HDD fragmentation.
Here are a few reasons why you may want to consider changing the block size of your drive from 4K to 64K:
- To improve performance for large files: If you have a lot of large files on your storage device, changing the cluster size to 64K can improve performance. This is because large files are typically stored in a contiguous block of space, and a 64K cluster size allows for more efficient storage of these files, resulting in improved performance.
- To save disk space: If you have a lot of small files on your storage device, changing the cluster size to 64K can save disk space.
- To improve compatibility with certain applications: If an application requires a specific cluster size, you should adjust the disk cluster size to meet that requirement, as some applications, like databases, may necessitate a cluster size of 64K.
Conclusion
Now that you know why changing the block size of your disk to 64K from 4K is a good idea, let's look at how to do it. We recommend using Qiling Disk Master, a user-friendly tool that can change the block size in just a few seconds, making it our go-to method. This makes it easy to upgrade your disk's performance with minimal fuss.
Qiling Disk Master offers several disk-related tools and is extremely easy to use, making it a complete no-brainer.
