Write back cache setting on Array P-400

‎11-30-2009 01:31 AM

Dear all,

 

       May some professionals advice me the performance on Write Back Cache Setting ?

 

I have a DB server, which is using P-400 for Raid 10,

 

now the setting is 100% read / 0% write,

 

if i buy a battery and set up as 25% read / 75% write, will it have better performance ?

 

is it big difference compare to 100% read only ?     URGENT , please advice . 

 

Thanks in advance.
