NTFS and FAT Performance
Summing up the influence of a brief performance on the disk controller and
system performance as a whole, one can say this: NTFS is suffering from a slow
drives much stronger than FAT. I would like to say a couple of words about the
amount of the cluster is the parameter that is on file systems FAT32 and NTFS
formatting can be set in almost random. First, it must be said that the large
cluster size is almost always greater speed. The size of the cluster to NTFS
Volume, however, has less impact on performance than the cluster size for the
system FAT32. A typical cluster size for NTFS-4 KB. It is noteworthy that with
the increased amount of deactivated cluster file system, built-in opportunity to
compress individual files, as well as standard API stop working defragmentation -
that is, the overwhelming number defragmentatorov, including built-in Windows
2000 will be unable to defragment this drive. SpeedDisk, however, he will be
able to work without the use of the API. The best in terms of speed, at least
for the medium and large files, it (Microsoft itself), the size of 16 kb.
Increase the size of further unwise because of too much spending on data storage
inefficiency, and because little further increase performance. If you want to
improve performance at the cost of loss of NTFS compression-think about
formatting of the disk cluster size, large than 4 KB. But keep in mind that this
will give a fairly modest increase speed, which often is not even reduce the
effectiveness of placing files on the disk. Performance System FAT32, on the
other hand, can be significantly improved by increasing the size of the cluster.
If NTFS cluster size almost no effect on the size and nature of the systemic
areas, the FAT system, increasing cluster twice, we are reducing the area FAT in
the same two-fold. Recall that in a typical system, FAT32 this very important
area for the performance took a few megabytes. Reducing the area several times
FAT will provide a noticeable increase in performance, as well as the volume of
system data file system greatly reduced, and reduced time spent on reading about
the location of data files, and the amount of memory required for buffering the
information. A typical amount for the cluster systems FAT32 is also 4 KB, and
increase it to 8 or even up to 16 KB - especially for larger (and more than a
dozen gigabytes) discs fairly reasonable step.
