Seagate seems set to replace its desktop Barracuda brand with the Desktop HDD brand and introduce a 4TB desktop drive with it.
The Desktop HDD 15 line runs up from 250GB through 320GB and 500GB all the way to 1TB, 2TB, 3TB and 4TB. It uses 1TB/platter technology, spins at 7,200rpm, has a 64MB cache, transfers data at up to 160MB/sec and uses the 6Gbit/s SATA interface. The 4TB product was announced in the Middle East via a press release which is not available on Seagate's US website. The release also claims Seagate has now produced 2 billion hard drives, four years after reaching the 1 billion level.
The 4TB desktop drive is mentioned on a Seagate Desktop HDD comparison data sheet (PDF), but there is no availability information available for it. A Seagate UK spokesperson confirmed that the drive is being announced. ®
