NTFS and FAT Performance
In this article I will try to evaluate the performance of file systems used in
operating systems Windows95/98/ME, as well as Windows NT/2000. Article does not
include graphs and test results, as these results are too heavily dependent on
the case, testing methods and specific systems, and have almost no connection
with reality. In this paper I will try instead to describe the general trends
and considerations related to the output file systems. After reading the
material, you will get information for reflection and will be able to draw
conclusions, to understand what system will be faster in your circumstances, and
why. Perhaps some facts to help you optimize the performance of their vehicles
in terms of the file systems, get some solutions that will enhance the speed of
operation of all the computer. The review mentions three-FAT system (hereinafter
FAT16), FAT32 and NTFS, as well as the fundamental question facing the users
Windows2000 is a choice between these options. I offer an apology to users of
other file systems, but the problem of choosing between the two, apparently
quite equivalent, options acutely now only available for Windows2000. I hope
nevertheless that the views expressed seem curious to you, and you can make some
conclusions and the systems with which you are working. The article is divided
into multiple partitions, each of which focuses on a single issue of performance.
Many of the sections in certain places are closely intertwined. Nevertheless, in
order not to turn art into porridge, in the relevant section, I will write only
that the discussion is relevant to the topic at the moment, and about anything
more. If you have not found any important facts in the text-not rush to wonder:
most likely you will meet them later. I ask you not to make any hasty
conclusions about the advantages and disadvantages of a system, as well as the
contradictions and pitfalls in these discussions very, very much. In the end, I
will try to collect everything that can be said about the performance of systems
in the wild. The most fundamental property of any file system, affecting the
performance of all operations of disc-structure of the organization and storage
of information, that is, it was, in fact, set up a file system itself. The first
section is an attempt to analyze precisely this aspect of work, that is Physical
work with the data structures and file system. Theoretical considerations, in
principle, may be missing are the ones who are interested in purely practical
aspects of performance file systems can apply immediately to the second part of
the article. To begin, I would like to point out that any file system in one way
or another store files. Access to data files, and the main part of working with
the file system, and therefore, first of all, you need to say a word about it.
Any file system stores data files in a certain volume-sectors, which are used as
sensors and the driver is the smallest unit of useful information drive. The
sector, in the vast majority of today's systems is 512 bytes, and all file
systems simply read the information and pass it without any processing
applications. Does there any exceptions? Virtually none. If the file is stored
in compressed or encrypted form as possible, for example, the system-NTFS is, of
course, to reinstate or decrypt information spent time and resources processor.
In other cases, reading and writing of the file data is carried out at the same
pace as the file system, you will not be used. Turn attention to the basic
processes carried out by the system to access files:
