256MB is not considered very large, not even for ext2fs. Ext2fs does however skip to another block group every X blocks (1MB on 1k systems?). This seek time is very small however, so it shouldn't really matter.
(big files start at 2G :)

Glibc allows async I/O.

Linux/ext2fs + glibc should be good enough. Use RAID and 1MB readahead for video streaming... If you need _really_ highend, you'd better get a machine with IRIX/XFS :)
