Our two samples were tested according to our standard hard drive testing methodology. Our methodology focuses specifically on noise, and great effort is taken to ensure it is comprehensively measured and described.
Performance is not tested, for reasons discussed in detail in the methodology article. For comprehensive performance testing about HDDs, we recommend Storage Review , who have established a strong reputation as the specialist in this field, doing nothing but testing HDD performance.
To get a good idea of where the drives in this review stand, it is important to read this article thoroughly. These two types of noise impact the subjective perception of hard drive noise differently depending on how and where the drive is mounted. Both forms of noise are evaluated objectively and subjectively. Both the subjective and objective analyses are essential to understanding the acoustics of the drives. Airborne acoustics are measured using a professional caliber SLM with absolute sensitivity below 0 dB.
Measurements are taken at a distance of one meter above the top of the drive using an A-weighted filter. Vibration noise is rated on a scale of by comparing against our standard reference drives. Its noise character is a bit harsh, as though there are several sharp peaks, but the total volume is quiet enough that it would not be intrusive in most systems. There is a very slight high frequency ringing that is audible within a foot or two of the drive.
Like the Barracuda IV, seeks are sharp and are much louder than the idle noise. Enabling AAM makes a dramatic difference. Both volume and sharpness are reduced immensely; AAM seeks are barely audible above the idle noise. Low vibration is not a strong suit of the DiamondMax Our first sample of the drive had the most vibration of any drive in the lab by a large margin.
In fact, we requested a second sample to confirm that the problem was not simply a result of sample variance. The second sample did indeed soften our initial verdict, improving our vibration evaluation by a single grade. Even the second sample still had more vibration than any other drive in the lab, although the difference was not as marked as in the first sample. The idle noise of the 7K is very smooth; it is similar in quality to the Seagate Barracuda IV our favorite reference drive , albeit a bit louder.
The difference in volume is at least partially caused by the higher number of platters in the Deskstar.
Close up, the idle noise sounded amazingly like the airflow from a fan. The noise has very little high frequency content, and constitutes a broadband whoosh or hiss depending on the angle you hear it from. Seek noise is average; it is not especially bad, nor is it particularly good. Most of the noise is a high-frequency clicking, but, unlike the Barracuda and the DiamondMax, they are not particularly sharp.
AAM has virtually no effect on the seek noise, although there is a touch of rumble when it is not enabled. Vibration is better than the DiamondMax, but not particularly impressive. Suspension would certainly benefit this drive. One of the general complaints about the Deskstar line in the past is the intermittent "head reset" noise that it makes every ten minutes or so when idling, and the 7K also exhibits this noise.

I think I now have a good contact there who really seemed to be kind of embarrassed how long it took Hitachi Support to get the DOS-Updater -wrong version or not- to me.
I've done a crude examination of several of the DOS downloaders, using the Unix "strings" program. The 5 x 5k 3tb drives i have came with 5C0.
I've been on the phone again with support and the 'Firmware Specialist' double-checked and confirmed that the DOS-Updater I received should work for my 0F drive, however EXE, too. Not at all. Given your effort to track down, and use, the Win "strings", you have converted yourself from a "hearsay witness" to an "eyeball witness".
May 13, 11 Performance-wise, things didn't change at all. Best regards, KrypteX P. For those who want to do it, the APM can be set to any value e. Last edited: Jul 21, TerroristTate New Member. Jul 26, 6 0 0. Hello all, I am having some issues that I hope you kind folks can shed some light upon!
These issues just so happen to coincide with what appears to be the primary topic of this thread. I have an Hitachi HTSB9A disk that produces click sounds, but not when it's intensely engaged in read activity, only when it's low activity. I'm afraid that the parking function can reduce the disk life: is there a way to disable the heads parking?
Post subject: Re: Hitachi disk click sounds: how to disable heads parking. What I suggested will normally works on your drive, and will survive reboot. I managed to start the Hitachi Feature Tool, but it only detects the Samsung Ssd and not the Hitachi disk: I think the latter is connected to a controller that may require a specific driver.
