PCMark05 Performance

We are utilizing the HDD test suite within PCMark05 for further comparative hard disk scores as it provides a mixture of actual application results and specific read/write percentages utilized within these programs. It is also a readily available benchmark that others can use for comparative purposes. The program utilizes the RankDisk application within the Intel iPeak SPT suite of tools to record a trace of disk activity during usage of real world applications. These traces are then replayed to generate performance measurements based upon the actual disk operations within each application. The HDD test suite contains 53% read and 47% write operations with each trace section utilizing varied amounts of read or write operations. Additional information about the test suite can be found in PDF format here PCMark05 whitepaper.

The PCMark05 test results are based upon the following trace runs:

Windows XP Startup: This test consists of 90% reading and 10% writes that tracks XP activities at start-up.

Application Loading: This test consists of 83% reading and 17% writes that tracks the opening and closing of the following programs.
  • Microsoft Word
  • Adobe Acrobat Reader
  • Windows Media Player
  • 3Dmark 2001SE
  • Leadtek WinFast DVD
  • Mozilla Internet Browser
General Hard Disk Drive Usage: This test consists of 60% reading and 40% writes that tracks application usage utilizing the following settings.
  • Opening a Microsoft Word document, performing grammar check, saving and closing
  • Compression and decompression using WinZip
  • Encrypting and decrypting a file using PowerCrypt
  • Scanning files for viruses using F-Secure Antivirus
  • Playing an MP3 file with Winamp
  • Playing a WAV file with Winamp
  • Playing a DivX video using the DivX codec and Windows Media Player
  • Playing a WMV video file using Windows Media Player
  • Viewing pictures using Windows Picture Viewer
  • Browsing the Internet using Microsoft Internet Explorer
  • Loading, playing and exiting a game with Tom Clancy's Ghost Recon
Virus Scanning: This test consists of 99.5% read operations as the test tracks the scanning activities of 600MB of files for viruses.

File Write: This test consists of 100% write activities by writing 680MB of files onto the hard disk.

Our PCMark05 numbers follow a familiar test pattern with the WD Raptor series having a significant advantage over the drives in our tests. The performance delta between the two 74GB drives is 6% with the major differences occurring in the General Usage and File Write sections of the test where writes are a very important part of the test. Our WD740ADFD has excellent write speeds and surpasses the WD1500ADFD in these particular write heavy tests while just trailing it in the read intensive tasks.

    That article certainly changed my perspective on Raptor performance. It's clear that the older 74 gig Raptor just can't hang with the big boys. I had heard that the new 74 gigger was the fastest, but your results seem to refute that entirely. The 150 gigger wins out more often than not. Reply

    Yeah I'm glad AT did this review as haven't seen much on the new 74GIG model. Now what I'd LOVE to see is how the new 36GIG models do in all of this and how 2 of them in RAID would compare to the bigger drives.

    Any chance of slipping in the new 36GIG model sometime Gary?

    Thanks for the review.:)

    Hi,

    We will have numbers on the 36GB ADFD in the next roundup. Also, we will be updating our RAID article from 2004 to see if the landscape has changed in regards to RAID 0 performance on the desktop but more importantly taking a serious look at RAID 1, 0+1, 10, and 5 on today's motherboard chipsets. We plan on this in March but the next HD article to go up will include the new 500GB drives from all suppliers.

    I find it surprising that the older model 74GB Raptor beats the new 74GB model in nearly every test. Reply

    heehee Never mind. I got the model numbers mixed up. :-)

    I find it even more interesting that a 320 GB 7200.10 beat out a 750 GB 7200.10 in a number of benchmarks.

    I also appreciate the mention of the Dell OEM Raptors with myself being a proud owner of a 160 GB Raptor :). (Which I got for a mere $160)
