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.
