PE 4600/PV220S Adding hard drive

I currently have a PE 4600 w/ 8 36 GB hard drives at 15K rpm.  Attached to this server is a PV220S.  The 220 has 8 36 GB hard drives at 10K rpm.
 
I would like to upgrade for of the drives in the 4600 to 146 GB drives.
 
I would then like to add the 4 36 gb 15K drives to the 220S.
 
Can I do an Add Member to my current array and add the 4 extra 36gb 15k drives to my array that is made up of 8 36gb 10k drives?  Was not sure if I could have drives of different speed in the same array....
 
If not I can make a new array with just those four drives....
 
Perc 3DC is my controller
Array Manager 3.4
Drivers/Firmware are all original, so they are still the same as what came on the server when it was bought 3 yrs ago.
 
Thanks.
 
Array in the 220S is currently Raid 5 and would be staying the same.

    PERC only matches drive capacity, not rotational speed, when creating arrays.  Dell specs all their SCSI 36GB drives at exactly the same logical block capacity so you should not have an issue when adding drives.    You probably want to create a new array, to take advantage of the lower 15K rpm latency, plus the bigger you make a RAID 5 the more drives are involved in every write operation.
     
    What may be an issue is your software/firmware.  There have been some significant upgrades to solve potential problems several years ago, so going to support.dell.com and getting the latest upgrades for both PERC firmware and Array Manager is highly recommended.
