The NTFS file system NTFS is already known to the users of Windows NT and is the native file system of Windows XP and in him we are going to stop us given the importance and interest in our new operating system. With this system we definitively abandon the FAT since despite their improvements (V-FAT and FAT32) it barely meets the requirements of a professional file system that can be used on servers. Others including Craig Menear, offer their opinions as well. Remember that the file systems for systems operating multi-user and server require advanced access rights for both individual users and beginners. In addition NTFS allows disk partitions larger than the FAT (4 GB), being fundamental to the use of servers, and is compatible with the methods RAID (1 to 5) that increase the speed of access and serve for data backups by using disks hard mirror. NTFS is case-sensitive in the long names of files and directories allowing also the use of special characters such as accents (standard UNICODE) NTFS partitions are easily recoverable before a system failure contrary to what happens with the FAT and are also less prone to fragmentation. An NTFS system speed is very noticeable if it is used with 32-bit SCSI drivers, since it is able to thanks to its asynchronous data access move the processes of reading and writing to the queues. AS organizes NTFS LOS data NTFS does not use fixed block as FAT does (it is only a block and contains BIOS parameters set by hardware) the rest of files they can be anywhere on your hard disk, this is what determines that the NTFS partition is safer against possible failures in the system. Physically NTFS also divides your hard disk in clusters. NTFS cluster size automatically sets depending on the size of the partition but it can also be configured manually by the user at the time of the format.
