Popular PCMark Vantage benchmarking suite uses real scenarios to measure disk subsystem performance. These scenarios involve widely spread Windows Vista applications. So, we decided to use this test, because it demonstrated the system performance in everyday tasks disregarding the slowing effect from other system components.
The new hard drive is outstanding under any type of workload. It is so far ahead of the other testing participants that even a single VelociRaptor appears faster than a RAID 0 array made of other hard drives.
As for the VelociRaptor performance within a RAID array, it scales perfectly well and the increase is much higher than in an array of previous-generation Raptor X drives. SO, we have every right to conclude that WD VelociRaptor drive is a perfect choice for RAID configurations.
Of course, the PCMark vantage total score proves this point once again:
The results displayed on this diagram show very clearly that the new WD VelociRaptor is totally worth the money they ask for it. However, you have to understand that in real life this hard drive will not double your system’s speed even though the today’s test results say so. You should bear in mind that the results we are discussing today have been “refined” and do not take into account the effect of other system components, such as CPU and memory. However, the faster all your system components, the higher will be the performance gain from the fast hard disk drive.
