NTFS and FAT Performance
FAT-minus: catastrophic loss of performance with increasing fragmentation,
especially for large disks (only FAT32). Difficulties with access to arbitrarily
large (say, 10% or more of disk size) files. Very slowdown Directory, containing
a large number of files. NTFS-pros: File Fragmentation is not practically any
effect on the file system itself is the work of fragmented system only getting
worse in terms of access to their own data files. complexity directory structure
and the number of files in one directory also shall not interfere special
performance constraints. Quick access to arbitrary snippet of a file (such as
editing large. wav files). Very fast access to files are small (a few hundred
bytes), the entire file can be found at the same place where, and system data (MFT
record). NTFS-minus: Significant demands on system memory (64 megabytes-the
absolute minimum, preferably more). slow drives and controllers without Bus
Mastering severely reduces performance NTFS. Working with a medium-sized catalog
so difficult that they almost always fragmented. Disk, long employed in a full
by 80% - 90%, will be to show very poor performance. I would like to emphasize
once again that, in practice, the major factor on which the performance of the
file system is, strangely enough, the memory of the machine. System memory 64-96
megabytes-a point at which performance NTFS and FAT32 roughly equivalent. Note
also the complexity of organizing the data on your machine. If you do not use
anything but the simplest applications and the operating system - it may happen
that FAT32 will be able to show higher performance and the large number of
machines with memory. - NTFS system, which conceptual for the future, and this
is the real future for the majority of applications today still, unfortunately,
probably not come. At the moment, NTFS ensures stable and indifferent to a
number of factors, but perhaps still on the low-typical "gaming" the home-system
performance. The main advantage of NTFS in terms of speed is that the system
insensitive parameters such as catalogs complexity (the number of files in one
directory), the amount of disk fragmentation, etc. FAT systems, however, each of
these factors lead to a substantial reduction in the speed of work. Only in the
complex high-performance systems-for example, the image stops or simply to
serious office computers with thousands of documents, or even more so in the
file-structure advantage NTFS be able to give a real performance gains, which
are sometimes visible to the naked eye. Users who do not have a large disks,
slaughtered information, and not using complex programs not expect miracles from
NTFS speed, in terms of performance on simple home systems much better show
itself FAT32.
