ReFS (Resilient File System) File System for Windows 8

Microsoft’s new Operating System Windows 8 is expected  to be launched in October-November of 2012. Microsoft has claimed this operating System as faster & best OS. Windows 8 is coming with a lot of new features. One of it's different & latest feature is that windows 8 come with new Generation file system ReFS (Resilient File System).



Use of File Systems:
The File System is use in OS’s to organize, store, retrieve, update your data and manage available space in Hard Drives. Hard Drives are made up of several circular platters& the tracks on these Hard Drives are divided into segments called Sectors. Each sector is of 512 bytes in size. File system manages the data in the form of clusters which is the smallest disk unit managed by operating system.
Before this Microsoft Launched FAT, FAT16 & FAT32. After this Windows Come With Advanced File System called New technology File System in 2003 which is used till now. NTFS is so Advance than FAT. 

But now Microsoft is releasing a new file system ReFS for its new Operating System Windows 8 Server. It has all the features of NTFS as well many other features.

What is ReFS File System:

RefS is the new file system which is also known as Photogon. ReFS uses following structured algorithm to index the data on the Hard Drive.
It allows each directory and file to grow its size with little impact on performance and speed which was the big disadvantage in NTFS File System. Right now ReFS file system will be implemented only on the Windows 8 Server and it will be available for Windows 8 at later stage. The basic to designing this ReFS, is to keep data safe and prevent OS from potential corruptibility.

ReFS will supported Maximum 4 PB (Petabyte, 1 PB = 1 Million gigabyte = 1 thousand terabyte) per storage pool and file length is 32,000 characters. In a single storage volume there will be 2^64 directories and in each directory there will be 2^64 files.

Features of ReFS File System:

• It Maintain highly compatibility with NTFS and also minimizes the ones with limited value at the same time.
• It verifies the corrupted data and correct this data automatically when possible.
• It provides metadata integrity with check-sums.
• An optional Integrity Streams are providing to users to integrate their data.
• It provides large volume, file and directory sizes.
• It gives better performance and removes data redundancy for fault tolerance.
• Disc scrubbing for protection against latent disk errors.
• Keep entire volume intact, online and accessible.
• It is highly scalable which explains why it is server only file system.
• It supports full set of Storage Spaces which will allow users to create storage pools from multiple physical and virtual storage devices.

The ReFS is also tested conditions like overloading & Sudden power failure.
