Seagate Technology expanded its lineup of mobile hard disk drives (HDDs) with new models that offer high performance and increased capacity. The introduction solidifies leading position of Seagate as the manufacturer of 2.5” form-factor HDDs.

The revamped product line now includes Momentus 7200.1, a 100GB HDD with 7200rpm speed and 10.5ms average seek time; Momentus 5400.2, a 120GB product with 5400rpm speed and 12.5ms average seek time as well as Momentus 4200.2 that offers 120GB capacity, 4200rpm speed and 12.5ms average seek time. The first two drives are offered for Serial ATA-150 interface and support NCQ (Native Command Queuing), which enhances performance of the models. Momentus 4200.2 is s available for Parallel ATA-100 interconnection.

“As notebook PCs displace desktop PCs in the workplace, end users increasingly will demand desktop PC capabilities in notebooks. Currently, the market for 7,200-rpm notebook drives is a niche market, but it is growing, and the market for 5,400-rpm drives already is growing rapidly. The market opportunities for these high-performance drives in notebook PCs also include requirements for higher capacities. Companies like Seagate that combine these capabilities with lower acoustic and power consumption levels will be well positioned in these growing segments to gain market share in the future,” said John Buttress, IDC's research manager for hard drives.

Seagate said Momentus 2.5” HDDs are also suitable CE devices, printers, copiers, non-mission critical blade servers, external storage arrays and other environments where systems are jostled or subject to high levels of vibration. Momentus drives can withstand up to 900Gs of non-operating shock and 250Gs of operating shock to safeguard drive data.

Seagate Momentus 7200.1 and 5400.2 are currently the world’s largest HDDs for notebooks among 7200rpm and 5400rpm models.
