While it is good news that Hitachi introduced this new disk, it is not alone. There is already the WD RE3 Enterprise 2TB, 7200rpm, 32MB, SATA2 disk, but finding it in stock is not easy and it holds quite a price tag currently. It is worth noting that the WD RE4 series are only 5400 RPM.
Thanks for the info Harm.
Here is some more data on the Hitachi drives (it turns out there are two models)
The Deskstar 7K2000 is built using a five-platter design, with each offering 400 GB of capacity. The Ultrastar A7K2000 is a four-platter design, with each platter offering 500 GB of capacity.
The Ultrastar A7K2000 is also rated at 1.2 million hours mean time before failure (MTBF), has a better unrecoverable error rate, and comes with a five-year warranty. The Deskstar 7K2000 does not have an MTBF rating, and comes with a three-year warranty.
Both drives are available. The Deskstar 7K2000 is currently shipping on an OEM basis via specific PC manufacturers, and will be available to the channel later this month. It is list-priced at $329. HGST is not discussing the list price for the Ultrastar A7K2000.
