ReFS (Resilient File System) is a file system developed by Microsoft as a successor to the NTFS file system. It was first introduced with Windows Server 2012 and is now available in Windows Server 2016 and Windows 10. In this article, we will look closer at ReFS vs NTFS and its features.
What is ReFS (Resilient File System)
ReFS (Resilient File System) is a file system designed for high scalability, availability, and reliability. Refs introduces new to address the growing need for data storage in modern data centers. ReFS (Resilient File System) is built on top of the NTFS file system, which has been used in Windows for over 20 years. ReFS supports a larger volume and file sizes and provides better data integrity and availability.
Resilient File System (ReFS) Features
- Data Integrity: ReFS (Resilient File System) is designed to provide enhanced data integrity by using checksums for file data and metadata. This ensures that any data corruption or errors are detected and corrected automatically. ReFS uses a 64-bit refs uses checksums for every 4 KB of data, which makes it much more robust than the NTFS file system.
- Scalability: ReFS supports larger volumes and file sizes than NTFS. It can support maximum file size volumes up to 1 YB (yottabyte), which is 1 trillion terabytes. This makes it suitable for use in large-scale data centers.
- Resilience: ReFS is designed to be more resilient than NTFS. It supports the automatic repair of corrupt data and has a faster recovery time in case of failures.
- Storage Spaces: ReFS works with Storage Spaces, which is a feature in Windows that allows you to pool multiple drives together to create a single virtual drive. Storage Spaces can provide redundancy, which makes them more resilient to drive failures.
- Integration with Windows Server: ReFS is designed to work seamlessly with Windows Server. It supports features like data deduplication, cluster-shared volumes, and file classification.
- Compatibility: ReFS is backward compatible with NTFS. This means that you can use existing NTFS volumes and file systems with ReFS.
NTFS vs ReFS: Comparison
NTFS (New Technology File System) and ReFS (Resilient File System) are two file systems developed by Microsoft. Microsoft’s newest file system. While NTFS has been around for over 20 years, ReFS file system introduced in Windows Server 2012. Here’s a comparison of the two file systems:
- Data Integrity: ReFS (Resilient File System) is designed to provide enhanced data integrity by using checksums for data and metadata. This ensures that any data corruption or errors are detected and corrected automatically. NTFS does not have built-in checksums, but it does have the ability to detect some types of corruption.
- Scalability: ReFS supports larger volumes and file sizes than NTFS. It can support volumes up to 1 YB (yottabyte), which is 1 trillion terabytes. NTFS supports volumes up to 256 TB.
- Resilience: ReFS is designed to be more resilient than NTFS. It supports the automatic repair of corrupt data and has a faster recovery time in case of failures. NTFS has some resiliency features, but they are not as robust as ReFS (Resilient File System).
- Features: NTFS has been around for a long time and has a wide range of features, including file support, file compression, encryption, and quota management. ReFS, on the other hand, is a newer file system and does not support some of these features.
- Compatibility: ReFS (Resilient File System) is backward compatible with NTFS, which means that you can use existing NTFS volumes and file systems with ReFS. However, NTFS is not forward-compatible with ReFS, so you cannot convert an NTFS volume to ReFS without reformatting.
- Support: NTFS is widely supported by third-party applications and is the default file name system for Windows. ReFS (Resilient File System), on the other hand, is a newer file system and has limited support for third-party applications.
- Snapshots: ReFS supports snapshots, which are read-only copies of a file system or volume at a particular point in time. NTFS does not have built-in support for snapshots.
- Storage Spaces: ReFS was designed to work with Storage Spaces, which is a feature that allows you to group physical disks into storage pools and create virtual disks from the available space. NTFS can also work with Storage Spaces, but ReFS (Resilient File System) was specifically designed to take advantage of this feature.
- Metadata: ReFS uses a different type of metadata than NTFS, which allows it to store more metadata per file. This can be useful in scenarios where you have a large number of files with extensive metadata.
- Block Cloning: ReFS (Resilient File System) supports block cloning, which is a feature that allows you to create a new file that references the same data as an existing file, without actually duplicating the data. This can be useful in scenarios where you need to create many copies of a large file. NTFS does not have built-in support for block cloning.
ReFS (Resilient File System) on Windows
While ReFS (Resilient File System) is an advanced file system that offers many advantages over NTFS, refs introduces not likely to completely replace NTFS on Windows anytime soon or starting with windows. Here are a few reasons why:
- NTFS is widely adopted: NTFS has been the default file system for Windows since Windows NT 3.1, which was released in 1993. Since then, it has been widely adopted by both consumers and enterprises alike. As a result, there are a large number of existing systems and applications that depend on NTFS, and transitioning to a new file system would require a significant investment in time and resources.
- Limited feature support: ReFS (Resilient File System), while offering many advantages over NTFS, still lacks some of the features that are available in NTFS, such as file compression and encryption. While ReFS is designed to work with Storage Spaces, a feature that is not available in NTFS, it is not yet widely adopted, and many systems still rely on other storage technologies.
- Compatibility issues: While ReFS is backward-compatible with NTFS, meaning that you can use existing NTFS volumes and file systems with ReFS (Resilient File System) , the opposite is not true. You cannot convert an existing ReFS volume to NTFS without reformatting the volume, which would result in the loss of all data on the volume. This creates compatibility issues, especially in mixed environments where both file systems may be in use.
- Performance trade-offs: While ReFS (Resilient File System) offers many advantages over NTFS in terms of data integrity, scalability, and resiliency, there are also some performance trade-offs. ReFS uses more system resources than NTFS, which can impact performance in some scenarios.
NTFS vs ReFS (Resilient File System) performance
ReFS (Resilient File System) can have slightly lower performance and newest file system than NTFS in some scenarios due to its increased focus on data integrity and resiliency features. However, refs introduces a data integrity and the performance difference between the two file systems is usually not significant and may depend on specific workloads and usage patterns.

Veeam recommends using ReFS when possible for backup repositories due to its advanced data integrity features, particularly in scenarios where data corruption may be a concern. ReFS checksums every 4KB of data, making it more resilient to data corruption and enabling faster data validation.
Converting an NTFS volume to ReFS
Converting an NTFS volume to ReFS (Resilient File System) can be done, but it requires reformatting the volume, which will result in the loss of all data on the volume. Therefore, it is essential to back up all data on the volume before attempting to convert it.
The ability to format a volume as ReFS (Resilient File System) is available in Windows 8.1 and later versions of Windows, including Windows 10 and Windows Server 2012 and later. However, it is important to note that not all editions of these operating systems support ReFS. For example, ReFS is not available in Windows 10 Home or Windows 10 Pro. It is only available in Windows 10 Pro for Workstations and Windows 10 Enterprise. Similarly, ReFS is only available in Windows Server 2012 Standard and Datacenter editions and later.
Here are the steps to convert an NTFS volume to ReFS:
- Back up all data on the NTFS volume to a separate location.
- Open Disk Management by right-clicking on the Windows Start button and selecting Disk Management.
- Locate the NTFS volume you want to convert to ReFS and right-click on it.
- Select Format from the context menu.
- In the Format window, select ReFS as the file system.
- Set any other desired options, such as allocation unit size and volume label.
- Click OK to begin the formatting process.
- Wait for the format to complete. This may take some time depending on the size of the volume.
- Once the format is complete, you can restore your data from the backup.
It is important to note that converting an NTFS volume to ReFS (Resilient File System) may not be necessary or desirable in all scenarios. ReFS offers advanced features such as data integrity, scalability, and resiliency, but it may also have some performance trade-offs, particularly in scenarios that involve many small files. Therefore, it is important to evaluate your specific use case before converting an NTFS volume to ReFS.
NTFS vs ReFS gaming
When it comes to gaming, there are generally no significant differences between ReFS and NTFS file systems. Both file systems are capable of providing adequate performance for gaming, and the differences between the two are more pronounced in other scenarios, such as data integrity and scalability.
ReFS vs ext4
ReFS and Ext4 are two different file systems that are used on different operating systems. ReFS (Resilient File System) is a proprietary file system developed by Microsoft and is designed for use on Windows Server and Windows 10 Pro for Workstations and Enterprise editions. On the other hand, Ext4 is an open-source file system used primarily in Linux distributions.
There are several differences between ReFS and Ext4:
- Scalability: ReFS is designed to handle large amounts of data and is optimized for use in data centers and enterprise environments. In contrast, Ext4 is designed for use on single systems and may not be as scalable.
- Data Integrity: ReFS has advanced data integrity features, such as checksums, that enable faster data validation and make it more resilient to data corruption. Ext4 also has some data integrity features, but they are not as advanced as those of ReFS.
- Resiliency: ReFS has built-in resiliency features that enable it to recover from data corruption or other errors more easily. Ext4 also has some resiliency features, but they may not be as robust as those of ReFS.
- Compatibility: ReFS is only compatible with Windows operating systems, whereas Ext4 is primarily used in Linux distributions. This means that the choice of the file system will depend on the operating system being used.
ReFS (Resilient File System) and NTFS are both file systems used in Windows operating systems. While both file systems have their strengths and weaknesses, ReFS offers advanced data integrity and resiliency features, making it a suitable choice for enterprise environments, whereas NTFS is a well-established and proven file system with good overall performance and compatibility with a wide range of applications. When choosing between ReFS and NTFS, users should consider their specific use cases and requirements, such as data integrity and resiliency, performance, scalability, and compatibility.

What is resilient file system?
A resilient file system is a type of file system that is designed to be highly fault-tolerant and resistant to data loss. It is typically used in enterprise-level storage systems where data reliability is critical.
Resilient file systems typically provide features such as redundancy, data mirroring, and checksumming to ensure that data is stored in multiple locations and can be recovered in the event of a hardware failure or data corruption. They may also include features such as snapshotting and replication, which can be used for backup and disaster recovery purposes.
What file systems does Linux support?
Linux supports a wide variety of file systems, both proprietary and open-source. Here are some of the most common file systems supported by Linux:
- ext2: The second extended file system is the default file system for many Linux distributions.
- ext3: An updated version of ext2 that includes journaling capabilities to improve data recovery in the event of a crash.
- ext4: A newer version of ext3 with support for larger file sizes and faster file system checks.

In addition to these, Linux also supports other file systems such as JFS, ReiserFS, ZFS, and many more. The choice of file system depends on the specific use case and requirements of the system.
Does ubuntu support NTFS file system?
Yes, Ubuntu supports the NTFS file system. NTFS (New Technology File System) is a proprietary file system developed by Microsoft and is commonly used on Windows systems. Ubuntu, being a Linux-based operating system, can read and write to NTFS partitions by default, but may require additional packages to be installed for full support. This means that you can access files stored on an NTFS partition from within Ubuntu, and also copy files to an NTFS partition. However, it is important to note that NTFS support on Linux is not as robust as on Windows, and some advanced features may not be available.
What causes NTFS file system corruption?
There are several reasons why the NTFS file system can become corrupted, including:
- Power failures: Abrupt power outages or unexpected shutdowns can cause data corruption in NTFS file systems, especially if write operations were in progress at the time of the failure.
- Physical disk errors: Bad sectors or other physical errors on the hard disk can cause data corruption in NTFS file systems.
- Software bugs: Bugs or errors in the operating system or third-party software can cause file system corruption.
- Malware or viruses: Malicious software can infect and corrupt files, folders, and even the entire file system.
- Human error: Accidentally deleting critical system files, formatting the wrong drive, or incorrectly configuring disk partitions can cause file system corruption.
- Overheating: Excessive heat can cause hard disk failure, leading to data corruption in the NTFS file system.
It’s important to note that while NTFS is a robust file system, it is not immune to corruption. To avoid NTFS file system corruption, it’s recommended to regularly back up your data, use reliable hardware, keep your system updated with the latest security patches, and use anti-virus software to protect against malware and viruses.
