Testing Participants

We are going to offer you a comparative test session with the following hard disk drive models:

  • Seagate Momentus 7200.1 ST910021A 100GB
  • Seagate Momentus 5400.2 ST9120821A 120GB
  • Seagate Momentus 5400.2 ST9100823A 100GB
  • Seagate Momentus 5400.2 ST9100824A 100GB
  • Fujitsu MHV2100AH 100GB
  • Toshiba MK1032GSX 100GB
  • Hitachi Travelstar 5K100 HTS541010G9AT00 100GB
  • Hitachi Travelstar 7K60 HTS726060M9AT00 60GB
  • Samsung MP0804H 80GB
  • Western Digital Scorpio WD800VE 80GB

You can refer to our previous articles on some of these models for more details. And now I would like to introduce to you those solutions that haven’t yet appeared on X-bit’s pages.

Seagate Momentus 5400.2 (ST9120821A) 120GB

The 5400.2 hard disk drive family includes not only the 120GB model we are looking at right now, but also the models with the following storage capacities: 100GB, 80GB, 60GB, 40GB, 30GB (by the way, the ST3100824A model that took part in our test session also belongs to this product family).

As you can guess from the name of the hard drive, the spindle rotation speed of this baby is 5,400rpm. The multi-segment cache buffer is 8MB big. The average seek time is 12.5ms, and the latency equals 5.6ms. The drive supports Ultra ATA/100 interface.

The power consumption of this drive is quite average: in the seek mode it consumes about 2.2W of power, and during reading and writing – about 1.9W. In idle mode the power consumption doesn’t exceed 0.8W, and in standby mode – 0.28W.

The drive can sustain an operational shock of 250 Gs for 2 milliseconds and a non-operational shock of 900 Gs for 1 millisecond. As for the acoustic characteristics of the drive it generates 2.4 bels of noise in the idle mode.

The dimensions of the drive are 9.5x69.85x100.2mm; its weight is 100 grams. The drives from this family use all Seagate’s brand name technologies that have already passed the test of time, such as SoftSonic FDB motor that improves the acoustics of the hard disk drive, and Quiet Step ramp load, which also allows to reduce the level of generated noise during operation and improves the shock resistance of the solution quite noticeably.

The drive is selling for approximately $250.
