Should You Care About Hybrid Hard Drives?

Battery Runtime Test

We again used the Acer Ferrari 1000 Turion 64 X2 notebook to compare the H-HDD to its counterpart with conventional technology. For the battery runtime test we installed a fresh copy of Vista and set the power mode to "power saver", which runs the CPU at a constant 800 MHz. The display was always on at two steps below the maximum brightness, and we set the power options to shut down the system at 1% battery status. The hard drives would spin down after three minutes, and the hybrid mode was enabled for the H-HDD.

The results here were a bit disappointing: using the H-HDD results in a battery runtime increase of two minutes, which represents a mere 3% improvement (at least it's something). Using the high-powered battery with 5200 mAh would result in about 172 minutes of runtime with the conventional HDD, and approximately 177 minutes with the H-HDD. Since the H-HDD requires even more power when spinning, expect the battery runtime improvement to decrease if the motor has to run continuously.
