In today’s world, some hard drives are simply better than others. Judging from data gathered from Backblaze.com, Hitachi Global Storage Technologies hard drives currently has the lowest annual rate of failures compared to other companies such Western Digital (which has recently come to acquire HGST) and Seagate. Although there is no gathering of scientific data to truly discern why some hard drives are better than others, common sense points us to few elements of manufacturing that tie in to the performance of today’s drives: bad/good design, technology, manufacturing defects and damaged goods.
The performance of a hard drive begins to take shape on the drawing board, and some drives are simply better designed than others; it’s often thought that the superior quality of Hitachi’s Deskstar drive emanates from its enterprise level quality assurance, meaning the drive goes through a higher level of testing and modification before being put on the shelf. The understanding of drive technology and accessibility of parts is also a huge factor, and companies like Seagate and Western Digital have been in the game much longer than most competitors, giving them a technological edge over the competition. Lastly, there is always the possibility of manufacturing defects and the hardware being damaged on its way to the store; a batch of bad motors or the hard drives being dropped by the shipping company are a common occurrence.
After considering these factors, it’s easy to see that no hard drive on the market is completely free of the possibility of crashing or failure. Although it is important to pick a high quality drive, the most important aspect of data storage remains unchanged: your must back up your data. In the end, even the best drive is at risk of crashing, so back up your data today.
