NTFS and FAT Performance

Search Data File Finding out of the areas in which the disk is kept a piece of the file, a process which is fundamentally different embodiment in various file systems. Keep in mind that this is only looking for information on the location of the file-access to their own data, fragmented or not, there is no longer seen as the process quite the same for all systems. It is about the "redundant" operations, which account for the system to perform real access to the data files. At that affects this option: the speed of navigating the file (access to arbitrary snippet file). Any work with large data files and documents if their size, and more than a few megabytes. This parameter shows how much file system itself suffers from the fragmentation of files. NTFS can provide quick search of fragments, since all the information is stored in several very compact Accounts (typical size of a few kilobytes). If the file is highly fragmented (contains many fragments), NTFS have to use a lot of records that often compel store them in different locations. The extra traffic heads in search of the data, in this case, lead to a severe slowdown in the process of finding data on the location of the file. FAT32, because of the very large area of table placement will have great difficulties if the file fragments scattered across the disk. The fact is that the FAT (File Allocation Table, table placement of files) is a mini-image disc, which includes each cluster. To access the snippet file system FAT16 and FAT32 have to apply to the relevant piece of FAT. If the file, for example, is located in the three-snippets at the beginning of the disk, in the middle, and end-the FAT system, we will have to turn to the FAT also snippet at the beginning, the middle and end. The system FAT16, where the maximum field size is 128 KB FAT, it is not a problem of the whole area-FAT simply stored in the memory, or read from the disk entirely in one pass and buffered. FAT32, however, is the typical size of the area around FAT hundred kilobytes, and the big disk-even a few megabytes. If the file is located in different parts of the disk is forcing the system to perform hard drive head movement as many times as groups of fragments in different areas is a file, and this very, very seriously slowing the process of finding fragments of a file.
