This does not square with my observations of behavior - I have seen smaller
paging I/O operations than 4KB, but never smaller than 512 bytes. A
non-cached I/O smaller than sector size isn’t really valid anyway.

Subject: [ntfsd] Can I presume the size of buffer of Paging IO is multiple
of 4K?
Hi all,
I am developing a file system filter driver and it seems to work very
well in most cases. In my driver, I always presume the size of Read/Write
buffer size is multiple of 4K when paging IO. Is that right? If not, can I
force IO manager always creates
multiple of 4K buffer?
Thanks in advance.
Cary
