There are new Seagate drives utilizing 1TB platters on the web and also in this Seagate document.

ST3000DM001 3.0TB 7200 3.5" Barracuda Internal Drive
ST2000DM001 2.0TB 7200 3.5" Barracuda Internal Drive
ST1000DM003 1.0TB 7200 3.5" Barracuda Internal Drive

More detailed spec are here:

Does anybody know the release date of these drives? Some shops on the web have already added them into the price lists.

I emailed Seagate last week asking when we'd see the 3TB 3 platter Barracuda. No release date yet...

Egad! I'm so glad I've stumbled on this post!

I just purchased a Seagate ST2000VX002 which on first comparison has identical specifications to the ST2000DM001 2.0TB - save for the rotational speed (5900 vs 7200) and intended use (standard vs video/surveillance).
My use is video storage in a HTPC only.

Looks like I may need to re-evaluate my decision.

Maybe...this post it a little old, they have since announced the death of green drives and the 1TB platters are shipping in the Barracuda.

ST2000VX002 (Seagate SV35) are not the same platters-- per the spec sheet at least, the areal density is very different.

422 Gbit/in^2 for the SV35 listed here, vs. 625 Gbit/in^2 for the new Barracudas with 1TB platters.

Aside from the spindle speed differences and whatnot, the lower areal density will likely result in lower performance (even if everything else was equal-- obviously one key factor not in these spec sheet races is head performance).

I'm confused about the 2TB drive. In this table from Anandtech:
http://images.anandt....20.26%20AM.png

it says that the 2TB version has 3 platters, so it's not likely using 1TB platters. Then in the table from StorageTux, the table says 2 platters for the 2TB disk, but its weight is the same as the 3TB one, which uses 3 platters. According to that table, all the disks which are using 1 platter weigh the same.

Is the 2TB disk using actually 3 platters, or is there a mistake with the weight?

[continuum]

The Seagate spec says the 2TB disk uses 3 platters, so it's probably using slightly lower-density platters. Mickey/doraemon or someone here (or on Ars Technica) explains it better.

As far as drive weight, manufacturers often generalize a bit on weights so it's harder to say what that means.

[Mickey]

As continuum said, it's likely that the 2TB that uses 3-disks is employing lower-density platters. It's not that different from what chip makers do, where they bin chips for speed/performance. Heads are treated the same way. Once built into drives, the manufacturer may discover that while the drive cannot reliably meet the highest target (e.g. 3TB), it may do just fine as a 2TB drive.

Of course, it may also be that whoever publishes the specs was lazy and just used the same value for all drives in the same "family."

THE DAY HAS COME... IT'S ON NEWEGG AS OF TODAY.

Seagate Barracuda ST1000DM003 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive
AVAILABLE TODAY on newegg. Searched this weekend and it wasn't there. Must have just arrived today

It's listed in the Newegg overview as "the Industries first 1TB-per-disk(aka platter)hard drive technology" drive so this is probably the one you've been waiting for. Rephrased, total size of Drive is 1TB with a single 1TB platter.
Buy it and let me know if it sucks or not before I buy it lolz

It's been there at least since November 11th because that's the day I posted about the apparent discrepancy in the specifications for other drives in the Barracuda family, and the day I was researching components on NewEgg.
