IPEAK Business Application Tests

IPEAK - Pure Hard Disk Performance

IPEAK - Pure Hard Disk Performance

Our IPEAK Winstone benchmarks offer a glimpse into how well our hard disk drives will handle general office applications, media encoding, and graphics manipulation. While the business applications that are being tested tend to be more CPU bound at times, the performance of the hard drive can and will make a difference in the more disk intensive video and graphics applications where large media files are typically being edited.

As expected the WD Raptor places first as its 10k rpm spindle speed and optimized cache play an important role in its ability to sustain high transfer rates, especially in the Content Creation benchmark where transfer block sizes are significantly larger than in the Business application benchmark.

The WD3200KS drive makes a very strong showing in these benchmarks compared to the Seagate 7200.10 320GB drive as it places 18% ahead in the Business Winstones and 3% in the Content Creation test. This continues the trend we noticed in the PCMark05 tests as the WD drive was generally faster in the general usage and application benchmarks. The Seagate 7200.10 drives continue to have issues with data that is not sequentially ordered on the drive.

IPEAK General Task Tests

The IPEAK based General Task benchmarks are designed to replicate utility based application tasks that typically are disk intensive and represent common programs utilized on the majority of personal computers. While the WinRAR program is very CPU intensive it will typically stress the storage system in short bursts. Our anti-virus benchmark will stress the storage system with continual reads and sporadic write requests while the defragmentation process is split between continual read and write requests.

The Seagate 7200.10 320GB turns the tables on the WD SE16 320GB drive by posting a 33% advantage in the defragmentation test, 12% and 5% in the WinRAR tests, and 8% in the AVG Anti-Virus test, a far cry from the 50% difference in the PCMark05 Anti-Virus test. Our antivirus IPEAK test file has a greater degree of randomness in the reads which creates a penalty for the Seagate drive compared to the PCMark05 tests. Overall, the pure hard drive performance of the Seagate drive in these daily application tasks is impressive.

    To avoid superparamagnetism, engineers have been increasing the coercivity, the field size required to write a bit, of the disc media. These fields are limited by the magnetic materials making up the write head that will soon effectively limit drive sizes utilizing longitudinal recording. Although additional capacities are still achievable, the drive industry will be moving to perpendicular recording technology shortly as longitudinal recording has basically hit the proverbial brick wall after being utilized for nearly 50 years."

    I wrote a pretty detailed post on the anandtech forums about this a while back. You can check it out http://forums.anandtech.com/messageview.aspx?catid...">here" (I used to post under the nickname "klaviernista"). Considering I examined and issued a lot fo the patents that are the basis of seagate's perpendicular technology, I think I am more than qualified to speak on the matter.

    Oh, and for the record, the "soft" magent under layer is never truly "written to" during the reocrind gprocess. The soft magnetic underlayer is made of a material that has magnetic domains which rotate easily in response to an external magentic field. When the write field goes across any given point in the medium, it induces the field in the corresponding point on the soft magentic underlayer to rotate perpendicular to the medium. The article is correct in saying that the result is a substantial increase in write field intensity, but neglects to mention that the fields of the soft magnetic underlayer to not remain oriented perpendicular to the media surface after the write field from the magentic head is removed, whereas the fields in the magentic recording layer do remain oriented perpendicular to the media surface.

    The whole point of usuing a soft magnetic underlayer is to allow magnetic materials with very high coercivity to be used as the recoprding layer. Why do you need a very high coercivity recording layer in high density recordng media? See the post I linked to above and read the discussed about "intergranular exchange coupling."

    Even with an extra platter to lug around, the Western Digital was quieter and cooler! Reply

    if you want to have the seagate hard drive cross shipped where they send you a replacement and you return the defective one back to them they charge $25, considering the hard drive cost $99, that there is a ripoff. I had this happen to me with a 250GB HD that I bought last year, so I'll be spending my money with one of the others unless the deal is ridiculous. Reply

    SPCR uses 1 meter (aka 1000mm or 200 times your stated distance) to measure SPL.

    "Each drive is measured for SPL one meter away from the top of the hard drive. Hard drive noise tends to be directional, the loudest position being directly over the top. SPL readings typically drop by 2~3 dBA/1m when measured from the side of the drive. The drive is placed on a soft foam to ensure that no vibration noise is produced during testing."

    The there is an entire category of sounds you hear at 5mm that wouldn't be noticable from outside a case.

    Take this quote from SPCR: "Consider the distance of Hardware.fr's recording microphone: 5cm from the HDD. This is a serious problem. There's no way the decibel reading can be accurate due to boundary effects. It's the same problem at storagereview.com -- not even relative differences are necessarily correct due to compression effects; the close proximity impacts every measurement similarly, reducing differences."

    http://www.silentpcreview.com/article631-page1.htm...">http://www.silentpcreview.com/article631-page1.htm... shows that the new audio recordings (not to be confused with the SPL Dba numbers) will use two recording distances:

    * One meter so that "nominal" volume, audibility, and sound character can be judged.
    * One foot (or 30 cm if you will) to capture all the details from even the quietest noise sources.

    The WD400YR and WD500YS seem very close to performance with the Raptor, but I can't find the WD400YR on pricewatch on newegg also I read about the WD drivers having a high rate of doa? Reply

    The Seagate drive has a performance advantage with the two 160GB platters. Anandtech is still ignoring the advantages of higher platter densities. Why is that? Platter density is one of the features I look at when purchasing a new drive. It's a good indication of performance when compared to another drive of the same total capacity. You have two 320GB drives reviewed with different number of platters and yet there is no mention of this other than the table. It's very odd. Reply

    On the last page it should be listed that the WD has a 3 year warranty for retail and 1 year for OEM - you have them switched. Reply
