I have already made logs larger then this on a 30GB partition so it should
be possible unless you are running in to some weird kfs issues. There was
one problem on a terabyte setup but those were inode problems.
A 15K RPM Cheetah or a solid state disk was probably the best after much
discussion :-)
So I'd say, yes, the faster disk. The raid array can probably work out the
throughput problems using many disks.
