Question : What is the fastest IDE hard drive available?

I'm having trouble finding any information about performance IDE hard drives.  I have an old server that could use a boost, but I'm stuck with IDE.

My first thought was an old WD Raptor, but I can't find any IDE variants.  Any ideas?

Sub queries can only be used in SQL statements.  Since this case statement is in PL/SQL not regular SQL, you cannot do it.

Either select the id into another variable or somehow join the selects into a single select statement ot return the desired type_id.

What does the following return:

SELECT   WAVELENGTH_TYPE_ID
              INTO   P_WAVELENGTH_TYPE_ID
              FROM   LAYER1_WAVELENGTH_TYPE
             WHERE   WAVELENGHT_TYPE_NAME = TDP_LOAD_SUMMARY_REC.Customer and
TDP_LOAD_SUMMARY_REC.Customer IN
                      ('CNI-CD',
                       'CNI-00',
                       'CNI-TC',
                       'CNI-M',
                       'CNI-RH',
                       'CNI-XC',
                       'CNI-NP',
                       'CNI-RT')
and
P_PROGRAM_ID IN (SELECT   PROGRAM_ID FROM   LAYER1_PROGRAM WHERE PROGRAM = 'MSP/DMX');
