Western Digital has also recently announced 2TB drives, but Seagate believes that its drives have the edge on other offerings. On the speed front, for example, with Seagate’s 2TB constellation drive running at a full 7200RPM while Western Digital's model operates at an eco-friendly undisclosed speed close to 5,400RPM. Given that as hard drives get more capacious it takes longer for them to seek out data, speed is an especially important concern, and key to enterprise customers.
The company is not releasing pricing details but merely describes them as competitive on price within the market. The 2.5-inch Constellation is expected to begin shipping before the close of the quarter, while the 3.5-inch Constellation ES is likely to arrive in the third quarter.
