Doubtless someone will come up with a more elegant solution than this, but at least it works!

SAM -> disks and filesystems -> disk devices.

This will give you a list of discs along with their model numbers. Type the model number into Google and you will be inundated with information about the disc - including speed.

Hi John,

try this "rude" way:
- go to SAM-disks and file systems-disk device
- on "description" column you can find disk model (i.e. ST39236LC for my SEAGATE)
- then on web site of supplier
you can find any kind of infos (like RPM)

hth

Hi,

Easier method could be as,
Use diskinfo command to findout the model number of your disk(Product id)


Eg:- #diskinfo /dev/rdsk/c18t0d0
SCSI describe of /dev/rdsk/c18t0d0:
vendor: HP 36.4G
product id: ST336607LC
type: direct access
size: 35566480 Kbytes
bytes per sector: 512
rev level: HPC5
blocks per disk: 71132960
ISO version: 0
ECMA version: 0
ANSI version: 3
removable media: no
response format: 2


search the model number ( ST336607LC ) in google search ( www.google.com ) to get the exact product data sheet, from where you can get the SPEED of your disk.

See one of the prod. data sheet .

If your disk is listed in /etc/disktab, look to see if it has an "rm" entry, this is the rpm for the disk.

e.g.

HP_7908:\
:16.5 MB:ns#8:nt#5:nc#404:\
:s0#16160:b0#8192:f0#1024:\
:se#256:rm#3600:


So a HP 7908 has a speed of 3600 rpm.
