IMHO there should be a 1 to 1 relation between mountpoints and physical disks. This will not make the disks faster but will make it possible to place databaseobjects on a specific physical disk, this will be handy when distributing IO over the disks..

I think he is refering to Oracle Striping : putting the data of a large table on more than one disk. When you have a table with 200Mb of data you can create 2 datafiles of 100 Mb on diffent disks and import the data. The IO on the table will be spread over two disks.
