Specifications, Pricing and Availability
Seagate has always done a very good job releasing information to consumers and journalists and the chart above is just a small slice of the data available. I think we should first start with the form factor of the new Constellation.2. Just saying 2.5" form factor isn't enough these days, since there are 7, 9, 12 and 15mm height drives on the market.
The Constellation.2 is the 15mm variant (technically 14.8mm), so you aren't going to be installing this drive in your notebook. The new Constellation.2 isn't designed for notebook use anyhow; the 15mm standard is reserved for server use and many server manufacturers have converted over to the 2.5" standard.
When it comes to the SATA version of the Constellation.2, the drive is available in 250GB, 500GB and 1TB capacity points. All capacity sizes are also available with encryption, but most shipped without encryption. All Constellation.2 drives use a massive 64mb cache buffer and have 7,200 RPM platters. Seagate has raised the bar again with this new series and moved the MTFB up to 1.4 million hours.
The Constellation.2 is the latest product from Seagate and has only been on the market a short time. We dug around and found the 1TB ST91000640NS drive available at PROVANTAGE for 206.93 USD. PROVANTAGE also gave us the lowest price for the 500GB Constellation.2 at 162.90. The 250GB model was a little more difficult to find since it didn't show up in the search at PROVANTAGE, but Google was able to deliver a link. This model runs 110.68 USD.
