After Western Digital introduced its first ever 2TB Hard disk, now its turn for Seagate to fire back with their 2TB Hard disk.Seagate’s 2TB constellation drive is expected this September and  is mainly exciting because it runs at a full 7200RPM while Western Digital’s model operates at an eco-friendly, undisclosed speed.

Given that as hard drives get more storage it only takes longer for systems to seek out their data, speed is an especially important point. Then again, Western Digital’s model is out now for $300. We’ll be curious what Seagate’s fatty Constellation goes for when it arrives later this year.

Seagate announced both the 2.5-inch Constellation and the 3.5-inch Constellations. Both drives will ship with either a SATA or a Serial-Attached SCSI interface, the Constellation will be Seagate’s first to ship with a SAS 2.0 interface.Seagate didn’t announce the prices of its Constellation drives.

After the review by Extremtech for Western Digital 2TB HDD they found that WD apparently sacrificed some performance for a quieter, lower-power drive. Seagate, on the other hand, says that the Constellation ES was the only 7200-RPM 2-Tbyte drive on the market.
