If you like the price and storage capacity of one firm can properly serve more than 3.5 years, and another – with high probability will fail within the first 1.5 years. To deepen your understanding Andreessen Horowitz is the source. And if your home computer is not as painful – a maximum of "burn" Archive photos from last year's tours, the dead drive corporate server paralyzes the entire company and "give" of the problem for several months. Even if the firm is protected by a backup data, it's like buying a short-lived hard drives, it will incur losses due to their frequent replacement and downtime for repairs. Hear other arguments on the topic with Ben Horowitz. In the laboratory, recovery Storelab.ru sought to determine whose hard drives usually last longer only. The measure of life most of the hard disks produced six vendors: Fujitsu / Toshiba, Hitachi, Samsung, Seagate and Western Digital.
To determine who makes the most reliable devices, we have analyzed the statistics of the proceeds of the failed drives. It was considered more than 4,000 devices from personal computers (3,5 ') to the laptop (2.5 "). Data analysis was compared with market shares of companies. Obviously, the more certain hard drives stamps have been sold, the greater the percentage of failed. Popular models come into the lab data recovery more often than not.
And the only significant difference in income and market share may indicate relatively high or low reliability. It turned out that the two sets of data correlate only partially. The main difference – the percentage of failed devaysov the market leader Seagate is almost 2 times its share: 56.1% vs 31%. Can make an amendment to the Russian specifics: on its own data Seagate, its share in the domestic market – more than 40%. But fundamentally, this situation does not change the fact: the percentage of the proceeds of "dead" drive is much higher market share. It indicates a lower reliability of Seagate hard drives compared to other manufacturers. All other suppliers share earnings below the market share, and a Western Digital and Hitachi difference of almost 11%. Thus, these devices companies are more highly available. The second important factor – the average age at the time of hard drive failure. He, again, varies depending on the manufacturer's drives, and often depends on "Good" model. During the design phase to determine the durability of the hard drive is difficult. Having developed the device, the company can hold only laboratory tests: the temperature, pressure, vibration, etc. But this study, as usually does not show all defects in design. The real test of endurance is still time. Flaws are becoming apparent for a year and a half. If most of the hard drive manufacturer's survived this threshold, products can be considered reliable.
