This is achieved as more strict production control, and a host of new technologies, such as Managed altitude heads or read-only reference that the recorded data. Considerable price in this case pays high reliability. Among the railway Form Factor 2.5 "can be distinguished car models that are resistant to shock and vibration, can withstand temperatures from -30 to +85 and altitude from -300 to 5000 m. An example is the family of Hitachi Endurastar. Discs are oriented on the application in the on-board systems of cars, but they can be put safely in any portable devices. Of course, reliability is worth the money: 'Auto Drive' three times more expensive than usual. The third council – Choose a railway capacity, based on their current and future needs.
In the form factor of 3.5, there are three categories of drives: odnoplastinnye, dvuhplastinnye, trehplastinnye and more *. The first category is best suited for placing the OS and applications: with a good performance, these drives smaller than the others and bask less likely to fail. Disk from the second category is necessary to put the second in a PC and a specially allocate to the database, game and multimedia files. Finally, high capacity drives – the solution for special occasions: to say nothing of disproportionately high costs, they are quite capricious in operation. Denial of such a drive immediately blocking access to massive amounts of data, and backup for obvious reasons, is complicated. The fourth and final advice – buy new wheels for legitimate commercial firms offering a full factory warranty (usually 3 or 5 years). Questionable location (the radio market, etc.) – Refuge gray imports, disks used, or after repair. Reliability of such production is much lower, and the warranty illusive. Slight savings can result in big problems – it is necessary to you? * At the time of this writing, typical of the total capacity of one, two, three or more plates – 120-250 GB 320-640 GB 750-1500 and GB, respectively.
