Laptop HDDs: Trying to catch up with Seagate
In the market for notebook hard drives, Seagate is just lingering after rivals.
While Fujitsu, Toshiba, Samsung and Western Digital have been selling their 320GB 2,5-inch hard drives for months, Seagate has just unveiled the 250GB Momentus 5400.4 HDD. Come on, Hitachi already 500 GB storage unit also offers in this category, the comparison in this case would not even be correct, as the Travelstar 5K500 we also presented achieved this capacity with 3 plates, compared to the 2 - plate models of the above - mentioned manufacturers.
Despite all this, Seagate has no reason to convene a crisis team, the Momentus 5400.4 series consists of 250, 200, 160 and 120 GB models equipped with very correct technology, the characteristics of which are summarized in our table below.
