Four years ago, recommended expansion of notebook hard drives, many notebook users friends face between SSD and how old-fashioned mechanical hard drive options hesitant. In my “radical” slow “disease three kinds of the disk upgrade the choose?” An article on the choice for this type of disk performance and data on the performance from a brief analysis has been done, I hope to have these problems you can refer to a friend . In fact, not the pursuit of extreme performance for friends, old notebook hard drive still has a high content of the bid, although years ago, did not drive the price down trend, but the SSD solid state drive or the price much higher. I recommend for everyone today, four traditional notebook hard drives, how to choose also need your own decision. Recently, Thinkpad T43 Battery
the phenomenon is more serious stock market, eager to expand computer capacity needed to seize the time a friend, otherwise I am afraid to get after the holiday to buy. Coincides with the Spring Festival, I ZOL consumer storage division on behalf of all members I wish you the reader, “the dragon down, fortune climb” in the new year, hope to get more light note with your support. Page 2: Hitachi 750GB laptop hard drive compatibility past two years, solid-state hard drive fast, and are more and more attention, but its contents were lower than the average consumer has always been prohibitive. Therefore, the laptop mechanical hard drive still has a broad market. End of the market price of the disc is relatively stable, there is a demand of friends can be considered for selection. Hitachi 750GB laptop hard drive compatibility Hitachi as the leader in notebook hard drive, good quality and good compatibility, favored by young users, as the first choice for mobile hard disk assembly. Today I introduce to you this 750GB portable hard drive is Hitachi’s hot models – 5K750,Thinkpad T61 Battery
its price was only 630. Hitachi 2.5-inch Hitachi 5K750 5K750 notebook hard work with excellent anti-vibration capability, the use of Thermal Fly-height Control (TFC) technology can reduce the soft error rate and improve the reliability and TrueTrack Technology? Can track high-vibration environments accuracy. Fluid dynamic bearing motor can achieve almost silent operation. These two series of hard disk components were reduced by the use of halogen, to support “green” computing initiatives, which the growing importance of today’s end users. Hitachi 5K750 500GB 2.5-inch notebook hard drive with 8MB of this 5400 RPM hard drive cache and SATA 3Gb / s interface for faster data transfer rate. Hitachi 5K750 hard drive products with excellent energy-saving features ultra-low power consumption, power consumption of only 0.5 watts of air operations, read / write operating power consumption of only 1.4 watts, which can extend notebook computers and other applications do not plug the battery life.

solid state drives expensive capacity is small, the two can not find a compromise point. However, before releasing a Seagate Momentus XT notebook hard drive, called the hybrid hard disk. The drive has a 500GB capacity, along with a 4GB of SLC flash memory chips, used to record the everyday use of the application file, for quick loading. The drive currently sells for 880 yuan, compared to a thousand dollars the price listed is indeed a lot cheaper, interested friends may wish to look. Seagate Momentus XT 500GB notebook hard drive package labels for the Momentus XT, its essence is a 2.5-inch 7200rpm high-speed mechanical drive, the largest with a 32MB cache, with a capacity of 4GB SLC NAND flash memory particles, then the controller manage what files will be stored to flash memory can be. Seagate Momentus XT 500GB notebook hard drive Seagate Momentus XT 500GB notebook look hard disk label from the label point of view, this Seagate Momentus XT 500GB notebook hard drive is a normal 7200 laptop hard drive capacity of 500GB, two-disc 4 head design. But it is above the PCB added 4GB of flash particles, see the following dismantling. Micron 4GB 4GB NAND flash memory chips for Fengyun, it is a newborn baby, mind blank, but it is developed by Seagate Technology Adaptive Memory intelligent memory can keep learning, to detect the use of high frequency data Information stored in flash memory,TOSHIBA PORTEGE 4005
and then once the software requires access to these data, we can directly read from the flash quickly, otherwise continue to access the disk. You know, read the information from the flash memory is much faster than the extract from the rotation of the disc information, it would appear, just as a Momentus XT hard drives are generally tailored for the owner. Seagate Momentus XT 500GB notebook hard drive on the back of another close-up, even if the user off, stored in flash memory data Momentus XT will not be lost, unless the format or defragment. And conventional hard drives, users still need to defragment the disk, but will flash through “learning” the preservation of the cache is cleared, so the best way to reduce the user’s hard disk defragmentation frequency. Comments: Seagate Momentus XT 500GB notebook hard drive combines the mechanical hard drives and solid state drives the respective advantages. It has large storage space, the application of intelligent load files for everyday use, user-friendly quick read.
