I have a 7gb primary partition.It is not the system partition.I wanna format it with NTFS.I wanna know what is the allocation unit size which gives the optimum performance.

Thank u

I think you will end up w/512
Good luck!

That is curious... I'm using NTFS in my 16 GB partition, and it formatted with a default alocation unit with 512 bytes in size... ;)

not too curious. 512 is the best it can do for any size volume. It would be nice to be able to change it to any number you wanted-but no go.
512 is the smallest I think.

you can boost performance by increasing cluster size ;) you can do it without having to format with PartitionMagic floppy set , even tho with would be 'wasting' space on HDD :)
it's all a matter of options :rolleyes:
cheers

found this thread while tracing topics started by tkr42 he he :D

mmm you can increase the performance by increasing the cluster size. but large amount of small files will take a large room in your disk e.g. a 56bytes will allocate 4kb from the disk. :o
to save disk space, i think formatting with the cluster size of 512bytes is better :)

But I prefer 4096bytes because I feel the disk operating at a better speed with it. Smaller cluster size also rises the fragmentation of files more than high cluster size.

But I've got my C: in 512bytes and D: on 4096bytes. I would have liked my C: to have the same size the D:'s got.
