Seagate Momentus 7200.4 | 500GB
4.5 Star Review  productwiki.com - Aug 19, 2011

The Seagate Momentus 7200.4 is a hard drive for laptops. It shares many features with the Seagate Momentus 7200 series, such as low power consumption and G-Force protection against dropping the laptops and so on and QuitStep technology that enables very quiet operation. However in addition it also has cache and on the fly error-correction algorithm. It also has a fluid dynamic bearing motor for quiet operation. With a 7200 RPM can shut the system down 34 percent faster and opening big files can be 30 seconds faster than a 5400 RPM drive can manage. This piece compares quite well with the 5400 series offered by Seagate(Seagate Momentus 5400.6). Its more quiet than Seagate Momentus 7200 FDE in the same series. Features Capacity (GB): 500 and 250 Interface: SATA 3Gb/s NCQ Cache (MB): 16 Spindle Speed (RPM): 7200 Shock, Operating: 2 ms (Gs): 350 Shock, Nonoperating: 1 ms (Gs): 1000 Acoustics, Idle, typical (bels): 2.3 Acoustics, Seek, typical (bels): 2.5 ... PROS: (1) firmware is updated at the factory, so newer units dont need an update by the user (2) file access speeds are very good, maximizes the 7200rpm functionality (3) quality control is very good, never find a defective unit out of the box (4) reliable operation over years of use (5) installs easily, system recognizes it right away ... CONS: (1) doesnt come with G-Shock protection at the hardware level, needs to be accounted for in the notebook you use it in
