It introduces reference counts into its metadata for copied regions. Features that are only available on ReFS (not on NTFS) are:īlock cloning in ReFS performs copies as a low-cost metadata operation rather than reading from and writing to file data. Of course, they also have different features, which are reasons why they are used in different cases. ReFS and NTFS have many same features, for example: BitLocker encryption, data deduplication, CSV support, soft and hard links, failover cluster support, access-control lists, USN journal, changes notifications, junction points, mount points, reparse points, volume snapshots, file IDs, oplocks, sparse files, named streams, thin provisioning, and Trim/Unmap. ReFS is designed to support extremely large data sets without negatively impacting performance, achieving greater scale than prior file systems. NTFS supports up to 256TB file size and volume size (64KB cluster size), while ReFS supports up to 35PB file size and volume size. If you use an SSD, the ReFS speed acceleration effect will be more obvious. Some users also make a benchmark on NTFS vs ReFS and the result is that ReFS is indeed faster than NTFS. In this aspect, ReFS is better because it provides some speed acceleration features. In these cases, if you don't have backup, it's more difficult to repair the corrupt data because there are few data recovery programs that support ReFS file system.
Note: There are some cases where ReFS fails to repair data.
At this time, if bad sectors occur in the data area, the data may be corrupted.Īs for the ReFS format, it supports automatic verification and repair, and does not require the chkdsk repair command, so the impact of bad sectors on the data is minimized. In NTFS format, sometimes it is necessary to use the chkdsk command to repair the disk, especially if the power is suddenly cut off. But ReFS is better because it doesn't need chkdsk command any more. Please keep reading.īoth NTFS and ReFS have tools to protect data. But which one is better? I will make a conclusion in this part.
What Is Resilient File System (ReFS) and How to Use It ReFS vs NTFSĪfter reading the above introduction, you may be confused still. Therefore, it can deliver both high performance and capacity efficient storage and improve the performance of virtualized workloads. Performance: ReFS introduces new features like real-time tier optimization, block cloning, and sparse VDL.Therefore, it can precisely detect and fix corruptions while remaining online Resiliency: ReFS introduces new features like integrity-streams, Storage Spaces integration, data salvaging, and proactive error correction.
Introduced with Windows Server 2012, ReFS (Resilient File System) is Microsoft's newest file system, designed to maximize data availability, scale efficiently to large data sets across diverse workloads, and provide data integrity by means of resiliency to corruption. What Is NTFS (Including Pros and Cons of It) What Is ReFS? After following this standard, those open-source programs can also be used in Windows.
Starting with Windows NT 3.1 published in 1993, it is the default file system of the Windows NT family. NTFS (New Technology File System) is a proprietary journaling file system developed by Microsoft. Introduction to NTFS and ReFS What Is NTFS?
