To all HDD users
Today, talk about a little useful set of modern hard disks, which can significantly reduce the noise from his work.
For those who have not heard about the AAM - Welcome to a cat.
Things really are not new and many of her in the course. But more people on it have not even heard.
So, I will not pull the cat’s tail - in most modern hard drives have this function, as AAM (Automatic Acoustic Management), allows on the verge of silence and performance. Physical meaning - management level of acoustic noise emitted by a block of magnetic heads for reading / writing. Changing the setting to influence the search path, when the head is moved along the radius of the disc to find the desired cylinder.
In most cases, programs (as the nominal change settings in Windows, I do not know) is a scale from 0 to 255 (sometimes - from 128 to 255). 0 (or 128) corresponds to the silence (minimum performance), all further - faster, higher, stronger!
Some manufacturers do not include this function, others are still at the plant exhibited a maximum for the most proizoditelnosti, and others - on the contrary, to have the glory of the quietest and “slow”. By the way, we should not think that setting to 0 (128) will do very much of the disc brakes. Since the disc has a constant frequency of rotation, linear reading speed is not changed. Increasing the access time to a specific sector (for reduced speed positioner). The minimum value of AAM increases the access time on average by 30%. Do not be afraid of these numbers - is unlikely you will ever need a “high” performance. But in addition to much noise from the falling of the drive to win may be marginally in power consumption and temperature devaysa, as well as its lifetime.
Change AAM setting in Windows can be many means - soft HDTune Pro, HDDLife Pro, Victoria, MHDD, Hitachi Feature Tool (not only on drives Hitachi) and I think, as something else. I take HDTune Pro (the free version does not) - the noise extrema of the difference can be evaluated directly in the program, I think, will be surprised.
More information about AAM can be read on IXBT.
Alternative Fiche this - use heavy body with thick soundproofed walls, a special cradle and boxes, to strengthen the drive all the screws, or using special pads, zoom system block away from the ears, etc.)
Who is not news - it’s indifference) A better answer, how do you refer to my reviews. What they need to add that extra, that should change? Reviews What devices are more interesting? Constructive criticism and fresh Misle will help me become better for you.
