Here are all the models currently in the database for this manufacturer and drive width. Entries are sorted into sections based on platter density, and then manufacturer drive family.

Some tips:

Drives using odd sizes are sorted into whatever size category that's closest. For example, drives using 150GB platters are sorted into the 160GB/platter section, and drives using 200GB platters are sorted into the 250GB/platter section.
The total capacity of the drive is shown beside each drive model.
A platter-head ratio is shown next to the total capacity tag in brackets. For example, a drive with a (1/2) ratio has one disk and two read/write heads. Drives that leave some amount of their platters unused in order to fit into a certain capacity (such as a 320GB drive based on a 500GB platter and two heads, which would have ~180GB space unusable) are marked as [short-stroked] next to the platter-head ratio accordingly.
Any special features (increased rotational speed, interface types, unusual platter designs and stuff like that) are noted where necessary.

Barracuda Green (5900RPM, 32MB cache, SATA-300 interface)

ST1000DL002 1TB (2/4)
Not very sure about this model's platter density. Seagate makes it seem like the Barracuda Green family is only meant to contain 1.5TB and 2TB models, but here we have a 1TB model with smaller cache and interface in stock at several retailers. I'm assuming the drive contains a pair of 500GB platters, so unless someone chimes in with a weight comparison between a 2TB/1.5TB Green and one of these, here it will stay.

Barracuda Green (5900RPM, 32MB cache, SATA-300 interface)

ST2000DL001 2TB (3/6)
Seagate doesn't list these in any of their PDF datasheets for the Barracuda Green family. They can be found within the plastic cases of the firm's GoFlex products, though. A 1.5TB model with similar specs should also exist, but I'm not going to add it until I see some solid proof that it exists for sure. (Someone on the Seagate forums had mentioned that their GoFlex came with the above 2TB model.)

Desktop HDD.15 (5900RPM, 64MB cache, SATA-600 interface)

ST3000DM003 3TB (750GB/platter) (4/8)
The "DM" in the model number suggests a 7200 RPM drive (historically, the 5900 RPM Barracuda Greens used "DL"), but according to an analysis, at least the 4TB unit above actually spins at around 5900 RPM. Going back on what you said about 5900 RPM drives, are you, Seagate? The company doesn't even give a specific rotational speed for these.

1TB/platter Section (all drives under here use platters that can hold 1TB of data apiece.)

Barracuda 7200.14 (7200RPM, 64MB cache, SATA-600 interface)

ST750DM003 750GB (1/2 [short-stroked])
ST1000DM003 1TB (1/2)
ST1500DM003 1.5TB (2/3)

ST2500DM001 2.5TB (3/5)
ST3000DM001 3TB (3/6)
*Like the similar WD Greens and Reds, the 2TB Barracuda ST2000DM001 can be found at random in a range of platter configurations - the 'perfect' two-platter version or two different three-platter models, which are slower and might also be less reliable. If you have an ST2000DM001 that weighs more than 600 grams, has a shallow (as opposed to deep and wide) depression on the cover (like this), and HD Tune reports a maximum read transfer rate of less than 190MB/s, you have a three-platter unit, and you may want to consider getting a refund.
*There seems to be another way to determine the platter count of an ST2000DM001 - by looking at the third character of the serial number. An 'E' seems to point to a two-platter unit. An 'F' seems to mark a three-platter one. For example, W1Exxxxxxx = two-platter, W1Fxxxxxxx = three-platter. Seagate might change this scheme at any moment, though, so watch out. Thanks to ~fzabkar for this info.
