Today, hard drives are the only available way to store large amounts of data, and perhaps considering one hard drive, we do not dwell on its volume: Yes, a dozen terabytes will be enough for an ordinary user almost for life. But in the corporate segment, the increase in the capacity of one HDD from 10 to 12 TB allowed to beat the psychologically important milestone-10 Petabytes per 42-unit rack, and now no one is surprised that the increase in the capacity of one disk from 14 to 16 TB means “only” 12.8 Petabytes in 42U rack, or 64 TB in 1U format. Or 90tb in a desktop 5-disk NAS such as the QNAP TVS-951X.
The disk controller contains rotational vibration sensors, whose readings allow you to adjust the position of the head above the track at the time of reading or writing, to eliminate the influence of neighboring hard drives. In multi-disk NASes, this system can significantly increase the speed of random access due to more accurate positioning of the heads and reduce the impact of its own vibration on the disk array. Interestingly, the vibration correction system tracks up to 8 hard drives in your NAS, roughly speaking-takes into account 8 sinusoids, folding with each other, and in the Pro-series, up to 24 drives are tracked.
Interestingly, the external hard drive looks like helium, and the characteristics of its parameters coincide with helium, but nowhere in the characteristics or operating instructions does not say that its body is filled with gas, unlike the EXOS series for data centers, where the use of this technology is directly indicated in the properties table.
Of course, today, when the competition in the HDD market has been reduced to a lazy confrontation between two companies, Seagate and Western Digital (plus HGST, plus Toshiba), the average corporate customer is interested in the volume of the drive, its price and reliability. To maintain customer loyalty, marketers are looking for some new technologies, and I do not know whether by accident or at the cost of incredible efforts, but the guys from Seagate hit the bull’s eye: Ironwolf Health Management technology was really in demand in the market. It was supported by all the leading manufacturers of network drives (NAS), and the average user in addition to the dull incomprehensible parameters of S. M. A. R. T. became available beautiful interface with diagnostics of the state of hard drives.
