One partitionable RAID-10, perhaps, then partition as needed. Read the discussion here about performance of LVM and RAID. I personally don't do LVM unless I know I will have to have great flexibility of configuration and can give up performance to get it. Other report different results, so make up your own mind.
On MySQL servers I always always use LVM, even if performance is critical there: Snapshots! They make it easy and efficient to do an online snapshot after just freezing the database for a second or three. - ask [1] http://lenz.homelinux.org/mylvmbackup/ -- http://develooper.com/ - http://askask.com/
