Windows 8 is coming with new features like Lock Screen, Home Screen, App Store, Windows Explorer and many more. For this brand new OS they have decided to come with a new Generation File System ReFS (Resilient File System).
The basic purpose of File System using 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 rotating around an axis. 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 Microsoft had launched Window XP, FAT16 and FAT32 (File Allocation Table with 16 or 32 bit) was used in Computer Systems.
After this Microsoft came up with NTFS (New Technology File System) in 2003 which is the most recommended and widely used file system till date.
ReFS system provides high security and better performance than the FAT file system. Microsoft is recommending NTFS 5 file system which has more advance features than the FAT.
efS is the newly engineered next generation 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 limitation 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 purpose after the designing this file system, is to keep data safe and prevent OS from potential corruptibility.
Maximum size that ReFS will support is 4 PB (Petabyte, 1 PB = 1 Million gigabyte = 1 thousand terabyte) per storage pool and file length is upto 32,000 (unicode) characters. In a single storage volume there will be 2^64 (about 18 quintillion) directories and in each directory there will be 2^64 files.
