adding extra disk subsystem for Proliant ML350 G3

we have a Proliant ML350 G3 server,in which Exchange is installed.

Also we installed GFI MailEssentials and GFI MailSecurity on the same server. after upgrading to the latest versions of GFI softwares, there a performance bottleneck in the disk subsystem.

The server has 2 processors, smart array 532 controller with 5 x 36.4 GB 10k Ultra320 drives configured as one RAID5 physical disk, and no HDD is installed.

generally what is the best way to increase the disk performance.

for example, should we add an external smart array controller and add more drives then move the Exchange Data files and Log files to the new arrays?

please advise for this and other options.
thanks

Do you want to increase performance or increase the storage, more disk capacity, more hard drives?

I want to increase performance. Storage is more than enough.

The performance of the server does not rely only on the HDDs but also on the RAM and CPU usage.

Check the RAM usage, CPU usage and then decide what can be done to increase the performance like increasing the ram or adding additional cpu.

You could try to
change to 15k drives
get a controller with a bbwc
get an external disk shelf so that you could put more hard drives in the same disk group/RAID

but as Prabhu wrote, it is possible that other parts of the system might be causing this
