Western Digital使用5400 rpm级硬盘使所有人感到困惑
The WD Red ‘5400 RPM Class’ NAS hard drives actually spin at 7,200rpm.
WD Red“ 5400 RPM類” NAS硬盤實際上以7,200rpm的轉速旋轉。

One of the key specifications present on any hard drive is how fast it spins, with 5,400rpm and 7,200rpm being the two most well-known spinning speeds. However, Western Digital is muddying the waters by classifying some of its 7,200rpm drives as “5400 RPM Class.” Confused? You’re not the only one.
任何硬盤驅動器上存在的關鍵規格之一是其旋轉速度,其中最著名的兩個旋轉速度是5400rpm和7200rpm。 但是,西部數據(Western Digital)通過將其7,200rpm驅動器中的某些驅動器歸類為“ 5400 RPM類”,使情況更加混亂。 困惑? 你并不是唯一的一個。
As Ars Technica reports, Western Digital marks some of its WD Red Network Attached Storage hard drives as having a Performance Class of “5400 RPM Class,” which suggests these drives spin at 5,400rpm. Even the firmware on the drives reports 5400 RPM, but spectral analysis carried out by Reddit user Amaroko has confirmed these drives are actually spinning at 7,200rpm.
正如Ars Technica報道的那樣 ,Western Digital將其某些WD Red Network Attached Storage硬盤驅動器的性能等級標記為“ 5400 RPM等級”,這表明這些驅動器的轉速為5400 rpm。 甚至驅動器上的固件報告的轉速為5400 RPM,但是Reddit用戶Amaroko進行的頻譜分析已確認這些驅動器實際上以7200 rpm的轉速旋轉。
Although many consumers may be happy to find the hard drive they thought spun at 5,400rpm actually spins much faster, meaning higher performance, there are other consequences. Faster spin speed means more power is used by these drives and just as importantly, they emit more noise. In a NAS setup, which is what these drives are marketed as being for, both power use and noise levels are important, and arguably more so than performance.
盡管許多消費者可能會發現他們認為以5400 rpm轉速旋轉的硬盤實際上旋轉得更快,這意味著更高的性能,但還有其他后果。 更快的旋轉速度意味著這些驅動器會使用更多的功率,同樣重要的是,它們會發出更多的噪音。 在NAS設置 (這是這些驅動器的市場定位)中,功耗和噪聲水平都很重要,而且可以說比性能更重要。
The use of “5400 RPM Class” therefore seems misleading, and Western Digital’s official response to the discovery does little to clarify the situation. A representative responded to Ars Technica’s enquiry with the following statement:
因此,“ 5400 RPM等級”的使用似乎具有誤導性,并且Western Digital對這一發現的官方回應并不能澄清這種情況。 一位代表回應了Ars Technica的詢問,內容如下:
“For select products, Western Digital has published RPM speed within a “class” or “performance class” for numerous years rather than publishing specific spindle speeds. We also fine-tune select hard drive platforms and the related HDD characteristics to create several different variations of such platforms to meet different market or application needs. By doing so, we are able to leverage our economies of scale and pass along those savings to our customers. As with every Western Digital product, our product details, which include power, acoustics and performance (data transfer rate), are tested to meet the specifications provided on the product’s data sheet and marketing collateral.”
“對于某些產品,Western Digital已經在“等級”或“性能等級”內發布了RPM速度多年,而不是發布特定的主軸速度。 我們還將微調選定的硬盤驅動器平臺和相關的HDD特性,以創建此類平臺的幾種不同版本,以滿足不同的市場或應用程序需求。 通過這樣做,我們能夠利用規模經濟并將節省下來的費用轉嫁給我們的客戶。 與所有Western Digital產品一樣,我們對產品的詳細信息(包括功率,聲學和性能(數據傳輸速率))進行了測試,以滿足產品數據表和市場營銷資料上提供的規范。”
It seems Western Digital could easily clear up any confusion by simply making the spindle speed clear as part of each drive’s listed specification. But for now, just be aware that the number you think represents spindle speed on Western Digital hard drives might simply be a performance class instead and not representative.
看起來Western Digital可以通過簡單地將主軸速度作為每個驅動器列出的規格的一部分來明確消除任何混亂。 但就目前而言,請注意,您認為代表Western Digital硬盤驅動器上的主軸速度的數字可能只是性能等級,而不是代表性能。
