NTFS and FAT Performance
Conclusion: The absolute leader is FAT16, it will never force the system to make
extra disc operation for the purpose. Then comes NTFS, the system also does not
require reading redundant information, at least until the file is reasonable
number of fragments. FAT32 is experiencing great difficulties, until reading
redundant hundred kilobytes from FAT, if your disk scattered to different areas.
Working with the impressive size files on FAT32, in any event, fraught with
great difficulty to understand where on the disk is a fragment of a file, it can
only be studied clusters entire file from the beginning, for processing once a
cluster (every 4 KB file in a typical system). It is noteworthy that when the
file is fragmented, but is compact heap of fragments, FAT32 does not
experiencing great difficulties, as well as physical access to the area will
also FAT compact buferizovan. Search free space This operation is done in the
event that you need to create a file from scratch or copied to a disk. Search
place in the physical data file depends on how information is stored on the disk
employment sites. At that affects this option: to speed the creation of the
files, especially large ones. Preserving or creating a real-time large
multimedia files (. Wav, for example), copy large amounts of information, etc.
This parameter shows how quickly the system will be able to find a place to
write new data to disk, and what operations it will have to be done for that. To
determine if it is clear whether the cluster or not, the system must be based on
the FAT FAT see one entry corresponding to this cluster. The size of one record
FAT16 is 16-bit, single record FAT32-32 bits. To find disk space may be required
to view almost the entire FAT is 128 KB (maximum) for FAT16 and to a few
megabytes (!), In FAT32. In order not to make the search space into a
catastrophe (for FAT32), the operating system had to go to various tweaks.
