Although the hard drive performance is not within the transmission, but in terms of the external transfer rate of the interface has been improved. From 2002 to the present, interface SATA from PATA to change, and now the SATA 3.0 interface, also began to spread, and even 300 yuan only the blue version of Western Digital 500GB hard drive also started using the interface.
As the current one of the three Western Digital hard drive manufacturers, the introduction of the hard disk drive products into the blue, green, black panel plate and three series, each series has a different performance and technology. One blue-plate products are main the mainstream market in performance and energy efficiency in doing a good balance. The blue disk is Western Digital 500GB SATA 3.0 interface, the first to use entry-level hard drives.
Blue WD5000AAKX 500GB Western Digital drive with blue label, that it belongs to the blue line and take the high road, for mainstream users.
Western Digital WD5000AAKX 500GB single platter 500G blue plate design, the disk cache is 16MB, hard disk with SATA 6Gb / s interface speed is 7200rpm, with IntelliSeek, IntelliPower, NoTouch (ramp load), and other technology, can effectively reduce power consumption and disk film rotation noise.
Western Digital WD5000AAKX are blue plate series, while the single platter 500G drives in the design to heat, power, probability of failure than the more-disc, etc. The design has improved.
As a result of a single platter design, so the hard disk becomes a deep groove back. Interface, Blue WD5000AAKX 500GB Western Digital drive with the mainstream SATA 6.0Gb / s standard design, you can see the back of the PCB board hard disk installation and design using negative, so the design of electronic components play a very good protection.
As used for storage capacity, one megabyte (MB) = 100 million bytes, one gigabyte (GB) = 10 billion bytes, 1 terabyte (TB) = 10000 billion bytes. Total accessible capacity varies according to changes in the operating environment changes. As used for buffer or cache, one megabyte (MB) = 1,048,576 bytes. Used for transfer rate or interface, megabyte per second (MB / s) = 100 million bytes / second, megabits per second (Mb / s) = 100 million bits / second, gigabit per second (Gb / s) = 10 billion bits / second.
1, question: we sell genuine licensed mobile hard disk is it?
Answer: we sell mobile hard drives are Western Digital hard drive manufacturers and original brand new authentic licensed manufacturer, place of origin in Thailand or Malaysia,
2 questions: Why do I get the hard drive capacity and the capacity claims does not match?
Answer: After the purchase of hard, careful people will find them in the operating system, hard drive capacity and the capacity of the official nominal match, must be less than the nominal capacity, the greater the capacity the greater the difference. Nominal 40GB hard drive, the operating system to display only the 38GB; 80GB hard drive is only 75GB; and 120GB hard drive is only 114GB. This is not a manufacturer or distributor shoddy deceive consumers, but manufacturers of hard disk capacity calculation method and the operating system caused by different calculation methods, the relationship between different units due to conversion.
As we all know, the computer is binary, resulting in the operating system so that the capacity calculation is based on a binary for each of 1024, every 1024 bytes 1KB, 1024KB as per 1MB, 1024MB each for the 1GB, as per 1024GB 1TB ; the hard drive manufacturers in terms of computing capacity is based on a hex per 1,000, 1,000 bytes per 1KB, 1000KB as per 1MB, 1000MB each for the 1GB, as per 1000GB 1TB, this difference between the two resulted in hexadecimal Hard disk capacity 'shrink'.
120GB hard drive for example: manufacturers capacity calculation method: 120GB = 120,000 MB = 120,000,000 KB = 120,000,000,000 bytes, which translates into the operating system method: 120,000,000,000 bytes / 1024 = 117,187,500 KB/1024 = 114,440.91796875 MB = 114GB.
Simple algorithm: hard disk capacity / 1024 * 1024 * 1024
80,000,000,000 / (1024 * 1024 * 1024) = 74.5GB
40,000,000,000 / (1024 * 1024 * 1024) = 37.25GB
Need to partition and format the hard disk, there are differences between the operating system, plus installation of the operating system behavior when copying files, hard drives will be up more space, so the operating system displays the hard disk capacity and nominal capacity would differences, the two types of hard disk capacity difference of about 5% -10% should be normal.
3 questions: the size of mobile hard disk in the end be? In addition to the power adapter is not required it?
Answer: 2.5-inch mobile hard disk as basic and the size of the two identity cards, and does not require an external power adapter
3.5-inch mobile hard disk base and the size of an ordinary brick building, and require an external power adapter.
4 questions: Western Digital HDD easily broken it?
Answer: the production of original Western Digital Hard Drive, Western Digital is the result of strict quality control checks multiple manufacturers, the factory less than 0.01% of the bad disk, since we are Western Digital distributor level, reducing the flow of mobile hard disk in the process of transport links, our professional packaging and delivery to your hand, the basic rate of the bad disk is no difference between the factory and manufacturers, so we purchased through the Western Digital HDD, problems are rare, you can feel comfortable buying.
5, question: If bad, what is the three-year renewal for free?
Answer: 1. Where in any one of our web site to buy Western Digital Hard Drive are in the 3-year renewal of the service for free within.
2. Renewals means you do not replace a full set of split over new mobile hard disk packaging.
3. Within three years of hard use in normal conditions, quality problems, you can enjoy this service.
