    Hi,
    i just want to clear some thought out.
    assuming that i have Raid5(3 disk 75GB each ) and i create 2 partitions if i split my database on those 2 partitions should i fill improvements in the performance or it will be just like put all databases on my one big Raid5 no need to partition them?

    I think you don't need partitions at all with R5.
    But I use to work with R10, so wait for other members opinions.

    What type of usage you have OLTP or OLAP?
    Also what is the growth of database in next 3 years?
    Based on that you could set the partition by splitting the database or seperating indexes & data differently.

    Hi,
    my question is only in the physical thought is there any different by splitting Raid5 disk into partitions or is it the as i can use this Raid5 as one partition.
    should i notice any performance improvements if i split this Raid5 into 2 partition?
    logic i should not see any improvements because it's on the same Radi5 and not partition on another Raid5. am i right?

    Yip, you are right. You will see no improvement by splitting the Raid5 into 2 partitions, so if there are no business reasons to do it then it isn't neccessary at all.
