ReFS to superceed NTFS
Here’s a good news for all Windows User as Windows officially declared the launching of Windows 8.
We know NTFS(New Technology File System) is a standard file system for Windows NT, including Windows 2000, Windows XP and all the versions of Windows till date. As NTFS was launced ,it superceded the FAT and HPFS(High Performance File System) and was very easily accepted by the users . The NTFS supported improved metadata by using advanced data structures to improve performance, reliability , robustness and disk utilisation. Also in addition to all these features it provided security access control lists(ACL) and file system journaling. Though there are some limitations in the NTFS in tems of file compression, maximum cluster size and volume size, filenames and alternate data streams.
So now Microsoft goes official by declaring to launch Windows 8 which would be based on Resilient File System(ReFS), which would be a succesor of the New Technology File System(NTFS).
Resilient meaning something marked by the ability to recover readily or in other words we can say capable of returning to an original position as after having been compressed. Well, its the physical meaning of resilient. Now this concept has been well utilised by the company who claims that Windows 8 will run on ReFS that will work with new generation of storage technologies and offer scalability.
The ReFS is a newly engineered file system offering storage technologies for new generation. It would be introduced only as a part of Window 8 server, which it used for all other versions of it. At the application level ReFS stored data will be accesible by the clients as in the case of NTFS data.
According to Steven Sinofsky, President, Windows and Windows Live Division”While NTFS is the widely used, advanced and feature-rich file system in broad use, ReFS has been architected and engineered for a new generation of storage technologies and scenarios“. Also adding to it he said “ReFS is built on the foundations of NTFS and will maintain compatibility with the older file system. At the application level, ReFS-stored data will be accessible from client devices just as NTFS data would be”
And of course, data stored on ReFS is accessible through the same file access APIs on clients that are used on any operating system that can access today’s NTFS volumes.
The key features of ReFS would be
- Metadata integrity with checksums
- Data stripping for performance and redundancy for fault tolerance
- Disk Scrubbing for protection against latent disk errors
- Shared storage pools across machines for additional failure tolerance and load balancing
- Optimizing the technology for extreme scale
- Maintaining a high degree of compatibility with the NTFS
Thus with all these features it would be providing a resilient architecture when used with storage space. ReFS also will provide advanced verify and auto-correct data capabilities.
