Raid disk speed


I'm trying to to determine the speed of my Raid Hot swappable disks.

I need to determine if each disk is ether 10,000 rpm or 15000 rpm. I know that each disk is 72GB in size:

I have tried to find this information ind/proc/diskinfo and using dmesg but no luck.

Hardware spec :

dl380 with P400 raid controllor

/dev/cciss/c0d3: (Smart Array P400) RAID 1 Volume 0 status: OK.
/dev/cciss/c0d3: (Smart Array P400) RAID 1 Volume 1 status: OK.
/dev/cciss/c0d3: (Smart Array P400) RAID 1 Volume 2 status: OK.
/dev/cciss/c0d3: (Smart Array P400) RAID 1 Volume 3 status: OK.

You could use "sudo lshw -C disk" to know various information about the disks, like the manufacturer and the model. Then you could just search google with the manufacturer and the model and it should provide you the RPMs of the disk. At least in my disk it works. But RAID's different...

Thanks tokico,

I'm using Redhat AS 4 but there seems to be no support for lshw.
