Unfortunately there should be at least 3 different FSs on different
spindles: one for NOV database (over.view), it carries big files,
so fragment/block could be {2048,4096}/8192; (2) different logs (news.*,
log,etc) - also big files; (2') history{,.pag} - huge files with random I/O;
and (3) news spool itself - a lot of tiny files, so frag/block should be
512/{1024,2048}, and about 10^6 inodes for 6G (you figures may be different
if you carries more or less alt.*, so the good idea to have different
FS for alt.binaries.* and the rest).
So the best configuration is several small (1-2G) disks for history,
NOV, logs. And all the rest big (4G) could be concatenated by ccd.

On 10G space, I'm afraid we loose a lot of space for extra i-nodes.
We'll get more than 13*10^6 i-nodes, and 'll have about 2*10^6
articles - even less if we like alt.{binaries,warez}.* :((
