Seagate’s New Model Numbering Scheme

We just received a Seagate Partner e-mail that indicates that Seagate is changing the product model numbering scheme.


As we can see, the model numbers have changed significantly relative to the current model number structures. In the current scheme The prefix ST3 means 3.5” drive, ST9 means 2.5” drive while the suffix AS is SATA, ES is Enterprise SATA, and SS is SAS. The numbers in between the prefix and suffix would be the size of the drive and then three numbers indicating model specifics.

A breakdown of the model number and what each means is this:


What we will end up with will actually be a simpler way to order Seagate drives. No more needing to know the various model numbers for whatever feature we want with a 500GB drive for example. With the new model number scheme the number will remain the same for the 320GB drive across all of is various feature sets while the model number will be specific to those feature sets.

It means that internally we can track all of the various feature sets for inventory purposes but our externally facing collateral will use the one model number to describe a 320GB drive. This makes for a much simpler presentation too.


Ultimately, when it comes to ordering product the new model numbering scheme will not make too much of a difference when searching our distribution channels for product. Now, we can search ST31000*SS to find any 1TB SAS drives, ST3500*NS to find any Enterprise SATA drives, and so on. After modifying our wildcard location to ST500* we will find any and all 500GB SKUs available to us. We can then use the same methodology as above to limit our search results to ST500MX* for Mission Critical 500GB drive models or ST*MX to bring up all Mission Critical products.

Note that not all distribution search engines support wildcard searches beyond dropping the asterisk at the end of some alpha characters.
