years ago, different voices of the hard disk market, after all, a head end of the year, every holiday,Automatic door, whether welcome or expansion of capacity installed, Ji price of ten dollars or so that everyone can accept. Although there are also a lot of friends that moment the price and lags far behind last year's difficult to accept,Automatic door, I advise everyone here has a good grasp of their feet at prices determined degree of rationality but also do not buy too much emphasis on a small range of care the price difference, enjoy the early morning, while consumer happy New Year ahead.
I recommend for everyone today is four desktop was equipped for large-capacity 3.0 hard drive. Per-platter technology is developing rapidly, the overall capacity increase very significantly, in the year 2012 there will be even higher specifications have 4TB. 500GB and 1TB on the market price gap is small, focusing on cost-effective under the premise of the following four high-capacity hard disk, or worthy of consideration.
there Ji days to the first month, and in the first recommendation in the final round of products, ZOL consumer storage industry members wish all our readers friends, our common interest in the hardware market to find more highlights, so that we make progress together!
the course of time pinpointing a single platter Hitachi 1T drive promotion
Hitachi hard drives as Seagate, Western Digital's competitors, the cost has been an absolute advantage, and also strive to introduce new products first one. The first is from the Hitachi 1TB hard drives, and the first listing of a single platter 1TB Hitachi hard drive product still shows Hitachi is constantly trying to win customers through more recognition. Today I visited the Zhongguancun learned, Hitachi 1TB 7200 RPM 32MB SATA3 single platter hard drive sells $ 800, interested friends can be considered a start.

we have just mentioned, single platter hard drive is currently the most important factor affecting mechanical, on the one hand to increase the capacity of a single platter hard drive can bring the total capacity of hard disk upgrade, but also conducive to the production cost control. In addition, the disc track density (number of tracks per unit area) increase represents the increased data density, so that when the disc in the hard work per revolution, the head can read more data, so in the case of the same speed , the greater its internal hard disk platter capacity the faster data transfer rate.

platter 1TB Hitachi hard disk with a new front shell mold, plate body with a previous generation is a mature technology , so not much change the overall thickness, and the old Disc 1TB hard drive similar. But the back of the PCB panel, it is the first time the use of Hitachi reverse design, to avoid causing damage to parts exposed bump or fall due.

Hitachi 1TB hard disk platter number HDS721010DLE630, belonging to Hitachi 7K1000.D desktop series, the motor speed of 7200RPM, said SATA3.0 6Gbps rate interface and 32MB cache. In addition, the origin of which drives China (Shenzhen), the use of a single platter 1TB technology, the voltage than the old Disc 1TB hard drive, 5V reduce 30mA, 12V lower 280mA, hard to further reduce heat, highlighting the advantages of energy saving .

from the left on the map to right for the hard disk motor controller, the main control chip and cache particles. The drive uses the same products and the previous generation of 1TB Disc LSI LOGIC chips, without going through the bridge and the serial to parallel data conversion, you can play real advantage of SATA drives to achieve the interface speed 600MB / s. However, motor controller and hard disk cache has been updated particles are optimized, which cache the product particles from the old DDR upgrade DDRII, exchange of process data faster.
summary: the market price has been hard to pick up after the holiday, single platter hard drive technology, the manufacturers also have their own signature product, this section Hitachi 1TB hard drive, once launched, a good market response. Years ago, planned to expand hard drive capacity can be considered a friend to start, 760 yuan price is a cost-effective.
