resizing/moving datafiles for performance ??

Guys,

the DB is on 8.1.6 / Win2K.

there entire DB ( 33 tables and 110 indexes) is in USERS tablespace.
the USERS tablespace has only one datafile USERS.DAT of size 12GB.

it's on 8 * 10 GB HDD with RAID 5.

we are facing performance bottleneck now.

V$SESSION_WAIT shows many rows for DB FILE SCATTERED READ and DB FILE SEQUENTIAL READ.
all these events wait for USERS.DAT to be read. it's a highly read OLTP site.

So,will moving the table and index data to different tablespaces with relatively smaller datafiles ( say 1 GB ) improve performance ?
OR
since it is on RAID5 , will moving make any difference ?

10-20 MB of data gets added to the DB daily. if resizing/moving improves performance,what should be the size of my datafile ?

kindly give me a solution guys.
TIA.
