Performance in PCMark 2005
PCMark05 is an updated version of the previous benchmark. Instead of File Copying, there is now a File Write trace. A new trace called Virus Scan is added. Its name is self-explanatory.
Again, we performed each test ten times and averaged the results.
The Hitachi is in the lead again. The Samsung is now closer to the drive from Western Digital but cannot overtake it.
We’ve got the same results in the Application Loading subtest: the drives from Western Digital and Hitachi are competing for first place and the latter wins again.
There is nothing new again: the standings are the same as in the previous version of this benchmark.
We’ve got the same leader but the other standings are different. The Samsung takes second place, being just a little faster than the Toshiba. The HDD from Western Digital has fallen far behind the others. Such sudden changes in the ranks are due to the fact that the drive’s caching algorithms affect its performance in this subtest. Most of the test is performed within the buffer as is indicated by the high data-transfer rates.
You might have predicted these results: Western Digital’s HDD has been showing excellent writing capabilities throughout this test session. The Samsung has modest performance here. It has very specific deferred writing algorithms and its write speed depends greatly on the type of load.
The HDDs from Hitachi and Western Digital share first place in this version of PCMark (it is good for WD that file writing is included into the benchmark as a subtest). The Samsung has the lowest overall rating.
