Best NTFS Cluster Size for boot drive?

My Windows 2000 Pro laptop has a c: partition and a separate D: partition.for data.

I've been searching for a reference on the best cluster size for a Win2K partition, but
can't find anything.

The C: partition is a 12G NTFS partition with a 512 byte cluster size. Would 2K be a
more desirable cluster size for faster performance?

Thanks!!!

Please use cross-posting instead of multi-posting. Answered in another

The default and optimal cluster size is 4K. If you convert a FAT32
partition to NTFS and if the partition is not aligned to a 4K boundary
you will end up with 512 byte clusters. To avoid the problem you can
align the partition before doing the conversion.

Not my usual habit. However, I noticed that microsoft.public.win2000.file_system only
had a total of 20 threads, so I was concerned that I had originally posted in a dying
newsgroup.
