HD Tach results for Seagate Momentus 7200.4 500GB
HD Tach results for Hitachi Travelstar 5K500.B |
According to HD Tach, the Momentus 7200.4 has an average read speed of about
85MB/s, which is 16-18MB/s better than the Hitachi 5K500.B as well as other Seagate and WD 5400rpm 500GB
notebook drives. Its read speed puts it in a class similar to the Samsung
EcoGreen 500GB and WD Green 2TB. These 3.5" drives have much higher areal density, which seems to compensate for the lower
rotational speed. Random access times were similar as well. All this indicates that the Momentus 7200.4 500GB is a pretty speedy, especially for a notebook drive.
The Hitachi Travelstar 5K500.B 500GB was similar in performance to the other 500GB 5400rpm notebook drive, except for random access time, which was slower by 2~3ms, at least on HD Tach.

HD Tune results were slightly different than HD Tach, with a bit slower transfer rate for both tested drives and a touch quicker access time for the Hitachi.
