As I understand NTFS directories are B-trees or something similar, so
there is no reason why you should be worried.

My vague experiences suggesting otherwise have to do with the W2K
recycle bin (moving to a loaded recycle bin can be painfully slow),
and temporary internet files. But those are probably Windows
Explorer's fault, not the filesystem's.

The other issue is handling small files.

I remember reading about a filesystem for Linux storing small files
directly in the inode, perhaps even storing multiple files, directory
entries and all, in a single disk block. Alas I can't remember which
filesystem it was, or if it was production-ready. The point is that
there is no such thing as *the* Unix file system, and it may be
possible to find one that is particularly SVN-working-copy-friendly.
