Seagate Momentus 7200.1 (ST910021A) 100GB

We should pay special attention to the 7200.1 drive model, because it boasts higher spindle rotation speed of 7,200rpm. As a result, it is certainly faster than its fellows working at only 5,400rpm speed. Besides the 100GB model that we had in our labs, this HDD family also includes solutions with 80GB and 60GB storage capacities.

The multi-segment cache-buffer of this drive is also 8MB big. The average seek time is 10.5ms, and the latency equals 4.2ms.

As for the power consumption it is not much higher than in case of the previous hard disk drive. In seek mode Momentus 7200.1 consumes 2.6W of power, during reading and writing – 2.4W, in idle mode - 0.95W, 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 800 Gs for 1 millisecond. The drive generates 2.5 bels of noise in the idle mode.

Just like the previously discussed model, this drive supports Ultra ATA/100 interface. The dimensions of the drive are 9.5x69.85x100.2mm; its weight is 0.115kg. The drive uses the same brand name technologies as the above mentioned model, such as SoftSonic FDB motor and Quiet Step ramp load.

The drive is selling for approximately $290.

Fujitsu (MHV2100AH) 100GB

The Fujitsu HDD offers 100GB of storage space and features 5,400rpm spindle rotation speed. The buffer is 8MB big. It demonstrates average seek time of 12ms and latency of 5.56ms.

During reading and writing operations the hard drive consumes about 1.9W of power. In idle mode the power consumption is 0.6W, and in standby mode – 0.2W. The drive can sustain an operational shock of 300 Gs and a non-operational shock of 900 Gs. The hard disk drive generates 2.6 bels of acoustic noise in the idle mode.

This solution supports ATA/6 (UATA/100) interface and is currently selling for around $195.
