Seagate Momentus 7200.3 320GB Notebook Hard Drive

HD Tach v3.0.4.0

HD Tach is a low level hardware benchmark for random access read/write storage devices such as hard drives, removable drives (ZIP/JAZZ), flash devices, and RAID arrays. HD Tach uses custom device drivers and other low level Windows interfaces to bypass as many layers of software as possible and get as close to the physical performance of the device possible.

Benchmark Results: The Seagate Momentus 7200.3 320GB notebook hard drive has great read and write speeds as seen in the benchmark results above. The disk starts out at nearly 90MB/s and then slows down to 40MB/s at the outside of the platter. All said and done, the average read speed was found to be 75.6MB/s with a write speed of 69.1MB/s.

Comparison Chart: When comparing the Seagate Momentus 7200.3 to other popular hard drives like the Western Digital Scorpio Blue 500GB and the Seagate Momentus 7200.2 200GB, you can see just how fast the drive performs. The Seagate Momentus 7200.3 destroys the older 7200.2 drive in all the benchmarks with the exception of the random access test. It also is significantly faster than the WD Scorpio Blue 500GB Hard Drive in all the benchmarks. The results of HD Tach’s CPU utilization test don’t mean much as the application has a +/- 2% margin of error and the results are within this range.
