allows you to see the real discount by comparing the current price with the previous price, which is the correct & real discount you will be getting. Sometimes online sellers don’t do this in order to show shoppers a larger percentage drop in the product price in the offer or promotion. The real offer or promotion is when you compare the current price with the previous price. Real offers and promotions are sometimes not as advertised. To ensure you are getting a good deal, Kanbkam job is to track those price changes for shoppers, store and graph them so that the shopper can know if the product is selling now at a good price compared to it's history or not. Shopping portals change products prices frequently, sometimes every hour. Or simply press your ear against the drive if you happen to have perfect is a historical price analysis portal for products selling in online shopping & eCommerce portals in the Middle East and North Africa, like Amazon AE, Amazon SA, Amazon EG, Jumia, Jarir, eXtra Stores, etc.
Reportedly, a decent smartphone with a suitable app that can do frequency analysis is enough, as long as you aren't in a noisy environment, and can get close enough to the drive to be tested. The nice thing is that you can easily verify this yourself. The spectral views of these recordings were captured from Adobe Audition.

Methodology: I placed each HDD on an empty cardboard box, put a Blue Yeti microphone at full gain directly above the drive (as close as possible without touching), and recorded the drive being powered up. I recommend viewing the album on imgur's website, to be able to see the descriptions below the images. If anyone has ideas what WD might have done to "cripple" performance of these drives, or why they "lie" about the 5400 rpm, then I'm all ears.Īll I'm saying is that the sound spectrum of these drives clearly indicates that the motor is spinning at 7200 rpm, not 5400 rpm! Therefore, it should be easy to tell the difference between the two.Īnd indeed, my WD80* drives happily hum at 120 Hz! Note that I'm not claiming that these drives perform as well as "real" 7200 rpm drives of a similar capacity/density. 5400 rpm on the other hand corresponds to 90 Hz.

Plus maybe integer multiples of that frequency (240 Hz, 360 Hz, 480 Hz, etc.), so-called overtones/harmonics. You see, 7200 rpm is equal to 120 rotations per second, which should manifest as a base frequency of 120 Hz. But then I took a microphone and started measuring. When someone on a German forum told me that they were actually 7200 rpm, I didn't believe them at first either. Last year, I bought a few of these drives myself (both WD80EMAZ-00WJTA0 and WD80EZAZ-11TDBA0). This also applies to the 10TB models and maybe more. TL DR: The popular WD80EMAZ and WD80EZAZ drives from WD Elements and My Book appear to run at 7200 rotations per minute (rpm), despite being advertised and self-reporting as 5400 rpm.
