7mm-thick HDD

     Seagate have officially announced their indecently-skinny Momentus Thin hard-drive, which breaks a few records by virtue of its 7mm thickness.  The 2.5-inch hard-drive is targeted at ultraportables and netbooks, and will offer 160GB and 250GB capacities along with 8MB of cache and a SATA 3.0Gb/sec interface.

The benefit of the 5,400rpm drive, Seagate claim, is that it offers a lower cost per gigabyte than a comparable 1.8-inch HDD.  That means low-cost computers can be made thinner – 90-percent of netbooks use 9.5mm 2.5-inch HDDs, the company claims – without inflating their price-tags.

As for what the price tag is, exactly, Seagate are keeping such details secret until the drive is released.  OEMs will have access to the Momentus Thin from January 2010.
