Need specification for Seagate's Barracuda 7200.11 and 7200.12 drives

[Barnard]

I am recently planning for the new PC at my home, and want to know specification about Seagate's Barracuda 7200.11 and 7200.12 drives. I am also looking for the numbers of heads/disks for this drives. For that I have searched on the web library for it but no anymore specification for this, I am doing this because I want to determine about what models have a single disk/platter configuration. The information which is provided over there is for Barracuda 7200.10 only. Is there any reason for this, why there is no more specification?

I don’t think that there is no more specification about it, and if you want to know about it then try to contact with the Seagate’s web site for the new product information. I am sure that they will have the latest information about your query. And the other way is that you can also contact with them. Try to get the specification from there only, I am telling this thing because they will surely provide you the perfect specification.

In the relevant Product Manual, you can check the table 1 in section 2.0, and also for the more product specification you should visit on the following link:

I think that you can assume the number of platters form the model number only. I mean that in ST31000538AS indicates that it has only 3 platters. And also ST35004(2)8AS has the 2 platters, and ST310003(4)0AS has 4 platters.
