Test SetupHitachi Travelstar DK23EB-20 (20GB, 5400RPM, 2MB)
The drive that we're looking at today is the MHT2060AH which is based on the Ultra ATA-100 interface. The drive is based on a two disk/three head design that comes with a formatted capacity of 60GB. Similar to the tests performed on our previous mobile 2.5-inch hard disk drives, we'll conduct the tests using a notebook to judge the drive's overall performance as well as power consumption.
The drive was installed into a Samsung NX10 (Centrino) notebook and installed with Windows XP Professional and MobileMark 2002. The MobileMark 2002 benchmark will give us an indication of the drive's direct effect on the notebook's overall system performance, as well as the battery life of the system. The results will tell us just how fast is the drive, and the amount of power drawn by the hard drive. Obviously, in order for us to have a better understanding of the above characteristics, we'll have to compare the results with other hard disk drives. We have the results of other 2.5-inch drives below drawn up for comparisons :-
Fujitsu MHS2030AT (30GB, 4200RPM, 2MB)
Seagate Momentus (40GB, 5400RPM, 8MB)
Hitachi Travelstar 7K60 (60GB, 5400RPM, 8MB)
Heat is also a major concern for 2.5-inch hard disk drives and as such, we'll be measuring the drive's temperature under similar mobile applications. In the tests, we will install the hard drive in a small 2.5-inch external USB 2.0 plastic enclosure that does not comes with any form of additional active cooling mechanisms. This will effectively simulate the environment found in such external drives, as well as most drive bays found in notebooks. A thermal probe is then attached to the underside of the drive, directly on the drive's motor. The temperature of the drive is then taken after approximately 15 minutes of rigorous seek activity simulated with IOmeter's default workload. The temperature of the drive will then be compared to the other drives listed above.
