Will be stored in your digital life style, ultra-compact My Passport Essential portable hard drive. WD uphold the quality of the hard disk section, using today's leading technology to meet current and future needs.
Dual USB 3.0 and USB 2.0 Compatibility: single hard drive, compatible with all of today's equipment, and a next-generation speeds. It is equipped with USB 2.0, the case can be allowed to upgrade to USB 3.0.
Transfer rate increased by 3 times:
Connect to this hard drive: ultra-high speed USB 3.0 port,
Access and save files as fast as USB 2.0, 3 times.
Transmission of a 2-hour high-definition movies only less than 5 minutes, not 14 minutes.
Performance may be due to the user's hardware and operating system configuration is different.
WD-quality, and say what:
20 years, millions of users worldwide trust by: WD hard disk storage data. The reasons for our success is that we understand the importance of your data, our top priority is to ensure that they are full.
WD SmartWare Software:

Password protection to protect your privacy:
Using password protection and encryption to prevent unauthorized access to the data being, so you sit back and relax.
Sales encrypted hard drive in restricted countries / regions, can supply non-encrypted version of models.
Directly through the USB port on a PC power supply. No separate power supply.
Take good care of our planet:
Our small product packaging using recycled materials, can minimize waste. We encourage you to recycle them.
Transfer rate: The new high-speed interface, the actual transfer rate of about 3.2Gbps (ie 400MB / S). Theoretical maximum rate of 4.8Gbps (ie 600MB / S).
USB3.0 to introduce full-duplex data transmission. 5 lines in the two used to send data, and the other two for receiving data, there is one is ground. In other words; USB 3.0 full speed can be synchronized to read and write operations. Previous versions do not support USB full-duplex data transmission.
Power has been increased to 150 mA load (USB 2.0 is 100 mA or so), the configuration device can be increased to 900 mA. USB 2.0 higher than 80% faster charging speed. In addition, USB 3.0 the minimum operating voltage from 4.4 volts to 4 volts, more power.
USB 3.0 does not use equipment, polling, instead of using an interrupt-driven protocol. Therefore, before a data transfer interrupt request, standby equipment, not power. In short, USB 3.0 support standby, hibernate and pause status.
The specification will be reflected in the USB 3.0 physical appearance. But the USB 3.0 cable will be more 'thick', this is because USB 3.0 data cable more than 2.0 4 internal lines. However, this is a USB 3.0 jack defects. It contains additional connected devices.
Hardware System: Although the hardware interface USB3.0 and USB2.0 same shape, but needs the support of hardware chip can achieve real USB3.0 transfer rate, the machine's motherboard supports the expansion card, or via both USB3.0 a good way, and now the mainstream has already begun in accordance with the USB3.0 motherboard design standards, and the original old desktops or laptops, you can only choose to do to open the corresponding expansion of USB3.0 expanded.
USB 3.0 impact:
The 12Mbps upgrade from USB 1.1 to USB 2.0, 480Mbps; / 40 times, from the USB 2.0 standard upgrade to USB 3.0 standard is only 10 times, 10 times the speed increase but this has great application significance, since USB3.0 data transfer rate reached 4.8Gbps, is much higher than other transmission standards such as IEEE 1394 data transmission usually 400Mbps - 3.2Gbps between
The claims (USB mobile hard disk Terminator) standards a new generation of eSATA 3Gbps data transfer rate only.
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 basic 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 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.
4. Artificial damage (such as falls, water) is not within the scope of new ones.
