It has been said how small the difference is - therefore in my opinion it
should remain at 8KB to maintain best average performance with all existing
platforms.
I say its best let the OS and mass storage subsystem worry about read-ahead
caching and whether they actually read 8KB off the disk, or 32KB or 64KB
when we ask for 8.
