Just curious, how would a NTFS perform in this scenario? As far as I remember, NTFS allows btree directory structures. Also NTFS allows per file compression, and "live" partition extension (making a logical drive spread across multiple disks, or extending the size of a logical partition on the current disk). It seems to me that NTFS has quite a bit of functionality, but how does it perform compared to UFS - under the 'general' and extreme cases (such as news). I personally would love to see support for NTFS in FreeBSD, and although I'm not saying I have the technical ability to implement it, I think I might start working on this as a little project in my spare time. File systems are cool, but I have no experience implementing one. Where should I start? I'm assuming there must be a few good references out there (I have a Tanenbaum book on OS's, which covers UFS and Filesystems a little), and I get the MSDN Enterprise Subscription stuff, so I'm assuming NTFS must be documented in there somewhere...
