ReFS. Benefits and prospects
Way to store anything usually implies some regularity, but if in human life it is not mandatory, then in the world of computers data storage without it is almost impossible. Reflected the order found in the file system – the concept is familiar to most users of different electronic devices and operating systems.
The file system can be compared to a kind of markup that defines how, where and what method should be recorded on the medium each byte. Appeared at the dawn of the electronic era of the first file system was very imperfect, as, for example, a Minix file system with a lot of limitations and used in the same operating system Minix, which later became the prototype of the Linux kernel.
But as time went on, there was a new file system, better and more stable. Today the most popular of them, at least among Windows users, is NTFS, which replaced FAT32, currently used, except that the flash drives of small volume and has a lot of drawbacks, of which the most significant is the inability to write files larger than 4 GB. However, not deprived of them and NTFS. So, according to many experts, it lacks efficiency, performance and stability, therefore, it is time to consider the creation of a more sophisticated file system capable of meeting the growing demands from the first server and client systems.
And now, in 2012, Microsoft introduced the Resilient File System or abbreviated ReFS –resilient file system, positioned in the role of alternative to NTFS, and in the future may replace it. In fact, ReFS is a continuation of the development of the NTFS, from which it was decided to remove all the excess, and not become popular, but instead add new features.
The new Resilient File System:
- Architecture using Storage Spaces (storage spaces)
- High fault tolerance. Errors the file system to NTFS, which led to the loss of data that ReFS will be kept to a minimum
- Isolation of damaged areas. In case of damage to areas of the file system access to recorded data can be obtained from under Windows operating
- Proactive error correction. Automatic scanning volumes for damage and use preventative measures to restore the data
- Automatic recovery subfolders and their associated files when metadata corruption
- The use of redundant recording for fault tolerance
- The maximum size of a volume in ReFS could reach 402 Exabyte Exabyte vs 18.4 NTFS
- On formatted with ReFS, you can write a file size of 18.3 Exabyte
- The number of files in one folder – 18 trillion. against 4.3 billion in NTFS
- The length of the file name and path – 32767 255 vs NTFS
What will be deleted:
- Support of data compression
- Data encryption using EFS
- Extended file attributes
- Hard links
- Disk quotas
- Support for short names and ID objects
- The ability to change the cluster size (still questionable)
What will be inherited from the NTFS:
- The access control lists (ACL)
- The snapshot volume
- The mount point
- Reparse points
- Creating and using symbolic links
- Record all occurring in the file system changes (USN journal)
Currently ReFS is in early testing, however, computer geeks can appreciate the advantages of ReFS already, and on the client system to Windows 8.1 or 10. You will need to perform the following registry tweak:
However, the use of ReFS on a regular basis is not recommended. First, the system is still flawed, and secondly, any possibility of conversion to ReFS and Vice versa is no third-party software third, if you accidentally lose or delete from ReFS formatted partition files recover them will be nothing, because the recovery programs that work with that file system yet.
Should I wait for the implementation of ReFS in the near future? C more certainty we can say that no. If she gets a practical application, the first server system, which will also happen soon, but Windows client users will have to wait after that for at least another five years. Suffice it to recall the implementation of NTFS on the client system, and then Microsoft it took seven years. But most importantly, that the special needs in ReFS simply no. That’s when you see on desktop computers zettabyte drives, then, perhaps, there will be ReFS for the hour, and we still only remains to be patient and wait.
