WD spreading false information


#1

The PDF file on WD5000AADS

http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-701229.pdf
states 21, 22 and 22 dB for the 500 GB drive…

but the page: http://www.wdc.com/en/products/products.asp?driveid=607
states 25, 29 and 26 dB for the same drive…


What are the correct figures on the acoustics for WD5000AADS? Anyone?

I believe the HTML page is incorrect.

You can confirm this by comparing other specs such as weight (1.61lb / 0.73kg), and power dissipation (6W, 3.7, 0.8, 0.8). These correspond to the weight and power dissipation of the 2TB drive in the PDF datasheet. The numbers for the 500GB are 0.99 lb / 0.45kg and 4.1W / 2.2 / 0.8 / 0.8.

The noise figures for the 2TB drive are 24 / 29 / 25, which would suggest that they are also for a 2TB drive.

Dear Bengt,

Thank you for contacting Western Digital Customer Service and Support. My name is Jose N.

It depends on the firmware, last link is the one we have on sale.

but the page: http://www.wdc.com/en/products/products.asp?driveid=607
states 25, 29 and 26 dB for the same drive...

I hope that we have met your expectations today and that you are satisfied with our service. If you have any further questions, please reply to this email and we will be happy to assist you further.

Sincerely,
Jose N.

Apparently there were problems with running the drive at such low noise lewels, otherwise they wouldn’t have changed whatever was changed in the latest firmware. This is unfortunate I think, since there are so few drives that have seriously low noise figures… Well I’ll just have to look further for my ideeal drive. :slight_smile:

But how does a difference in the firmware account for a difference in the weight? :slight_smile:

These data specs are filled by a random numbers generator :wink:

It doesn’t matter anyway because when you buy one there is another random generator stearing the robot picking a drive from storage for shipping. Capacity is then copied from your order onto preprinted logo labels and placed on top of drive for your identification… so you know what drive you recieved.

Well anyway, happy 1’st of april…

No offence intended, I love my WD Green-drives, having departed from being an exclusive Seagate user of 20 years… :wink:
